Fix integration tests on AWS (#978)

Update groups permissions validation to use Table ACL cluster (#979)

Renamed columns in assessment SQL queries to use actual names, not aliases (#983)

<!-- Summary of your changes that are easy to understand. Add
screenshots when necessary -->
Aliases are usually not allowed in projections (as they are replaced
later in the query execution phases). While the DBSQL was smart enough
to handle the references via aliases, for some setups this results in an
error. Changing column references to use actual names fixes this.

Added group members difference to the output of `validate-groups-membership` cli command (#995)

The `validate-groups-membership` command has been updated to include a
comparison of group memberships at both the account and workspace
levels, displaying the difference in members between the two levels in a
new column. This enhancement allows for a more detailed analysis of
group memberships, with the added functionality implemented in the
`validate_group_membership` function in the `groups.py` file located in
the `databricks/labs/ucx/workspace_access` directory. A new output
field, "group\_members\_difference," has been added to represent the
difference in the number of members between a workspace group and an
associated account group. The corresponding unit test file,
"test\_groups.py," has been updated to include a new test case that
verifies the calculation of the "group\_members\_difference" value. This
change provides users with a more comprehensive view of their group
memberships and allows them to easily identify any discrepancies between
the account and workspace levels. The functionality of the other
commands remains unchanged.

Improved installation integration test flakiness (#998)

- improved `_infer_error_from_job_run` and `_infer_error_from_task_run`
to also catch `KeyError` and `ValueError`
- removed retries for `Unknown` errors for installation tests

Expanded end-user documentation with detailed descriptions for workflows and commands (#999)

The Databricks Labs UCX project has been updated with several new
features to assist in upgrading to Unity Catalog. These include various
workflows and command-line utilities, such as an assessment workflow
that generates a detailed compatibility report for workspace entities
and a group migration workflow to upgrade all Databricks workspace
assets. Additionally, new utility commands have been added for managing
cross-workspace installations, and users can now view deployed
workflows' status and repair failed workflows. A new end-user
documentation has also been introduced, featuring comprehensive
descriptions of workflows, commands, and an assessment report image. The
Assessment Report, generated from UCX tools, now includes a more
detailed summary of the assessment findings, table counts, database
summaries, and external locations. Improved documentation for external
Hive Metastore integration and a new debugging notebook are also
included in this release. Lastly, the workspace group migration feature
has been expanded to handle potential conflicts when migrating multiple
workspaces with locally scoped group names.

Release v0.14.0 (#1000)

* Added `upgraded_from_workspace_id` property to migrated tables to
indicated the source workspace
([#987](#987)). In this
release, updates have been made to the `_migrate_external_table`,
`_migrate_dbfs_root_table`, and `_migrate_view` methods in the
`table_migrate.py` file to include a new parameter `upgraded_from_ws` in
the SQL commands used to alter tables, views, or managed tables. This
parameter is used to store the source workspace ID in the migrated
tables, indicating the migration origin. A new utility method
`sql_alter_from` has been added to the `Table` class in `tables.py` to
generate the SQL command with the new parameter. Additionally, a new
class-level attribute `UPGRADED_FROM_WS_PARAM` has been added to the
`Table` class in `tables.py` to indicate the source workspace. A new
property `upgraded_from_workspace_id` has been added to migrated tables
to store the source workspace ID. These changes resolve issue
[#899](#899) and are tested
through manual testing, unit tests, and integration tests. No new CLI
commands, workflows, or tables have been added or modified, and there
are no changes to user documentation.
* Added a command to create account level groups if they do not exist
([#763](#763)). This commit
introduces a new feature that enables the creation of account-level
groups if they do not already exist in the account. A new command,
`create-account-groups`, has been added to the `databricks labs ucx`
tool, which crawls all workspaces in the account and creates
account-level groups if a corresponding workspace-local group is not
found. The feature supports various scenarios, including creating
account-level groups that exist in some workspaces but not in others,
and creating multiple account-level groups with the same name but
different members. Several new methods have been added to the
`account.py` file to support the new feature, and the `test_account.py`
file has been updated with new tests to ensure the correct behavior of
the `create_account_level_groups` method. Additionally, the `cli.py`
file has been updated to include the new `create-account-groups`
command. With these changes, users can easily manage account-level
groups and ensure that they are consistent across all workspaces in the
account, improving the overall user experience.
* Added assessment for the incompatible `RunSubmit` API usages
([#849](#849)). In this
release, the assessment functionality for incompatible `RunSubmit` API
usages has been significantly enhanced through various changes. The
'clusters.py' file has seen improvements in clarity and consistency with
the renaming of private methods `check_spark_conf` to
`_check_spark_conf` and `check_cluster_failures` to
`_check_cluster_failures`. The `_assess_clusters` method has been
updated to call the renamed `_check_cluster_failures` method for
thorough checks of cluster configurations, resulting in better
assessment functionality. A new `SubmitRunsCrawler` class has been added
to the `databricks.labs.ucx.assessment.jobs` module, implementing
`CrawlerBase`, `JobsMixin`, and `CheckClusterMixin` classes. This class
crawls and assesses job runs based on their submitted runs, ensuring
compatibility and identifying failure issues. Additionally, a new
configuration attribute, `num_days_submit_runs_history`, has been
introduced in the `WorkspaceConfig` class of the `config.py` module,
controlling the number of days for which submission history of
`RunSubmit` API calls is retained. Lastly, various new JSON files have
been added for unit testing, assessing the `RunSubmit` API usages
related to different scenarios like dbt task runs, Git source-based job
runs, JAR file runs, and more. These tests will aid in identifying and
addressing potential compatibility issues with the `RunSubmit` API.
* Added group members difference to the output of
`validate-groups-membership` cli command
([#995](#995)). The
`validate-groups-membership` command has been updated to include a
comparison of group memberships at both the account and workspace
levels. This enhancement is implemented through the
`validate_group_membership` function, which has been updated to
calculate the difference in members between the two levels and display
it in a new `group_members_difference` column. This allows for a more
detailed analysis of group memberships and easily identifies any
discrepancies between the account and workspace levels. The
corresponding unit test file, "test_groups.py," has been updated to
include a new test case that verifies the calculation of the
`group_members_difference` value. The functionality of the other
commands remains unchanged. The new `group_members_difference` value is
calculated as the difference in the number of members in the workspace
group and the account group, with a positive value indicating more
members in the workspace group and a negative value indicating more
members in the account group. The table template in the labs.yml file
has also been updated to include the new column for the group membership
difference.
* Added handling for empty `directory_id` if managed identity
encountered during the crawling of StoragePermissionMapping
([#986](#986)). This PR adds
a `type` field to the `StoragePermissionMapping` and `Principal`
dataclasses to differentiate between service principals and managed
identities, allowing `None` for the `directory_id` field if the
principal is not a service principal. During the migration to UC storage
credentials, managed identities are currently ignored. These changes
improve handling of managed identities during the crawling of
`StoragePermissionMapping`, prevent errors when creating storage
credentials with managed identities, and address issue
[#339](#339). The changes
are tested through unit tests, manual testing, and integration tests,
and only affect the `StoragePermissionMapping` class and related
methods, without introducing new commands, workflows, or tables.
* Added migration for Azure Service Principals with secrets stored in
Databricks Secret to UC Storage Credentials
([#874](#874)). In this
release, we have made significant updates to migrate Azure Service
Principals with their secrets stored in Databricks Secret to UC Storage
Credentials, enhancing security and management of storage access. The
changes include: Addition of a new `migrate_credentials` command in the
`labs.yml` file to migrate credentials for storage access to UC storage
credential. Modification of `secrets.py` to handle the case where a
secret has been removed from the backend and to log warning messages for
secrets with invalid Base64 bytes. Introduction of the
`StorageCredentialManager` and `ServicePrincipalMigration` classes in
`credentials.py` to manage Azure Service Principals and their associated
client secrets, and to migrate them to UC Storage Credentials. Addition
of a new `directory_id` attribute in the `Principal` class and its
associated dataclass in `resources.py` to store the directory ID for
creating UC storage credentials using a service principal. Creation of a
new pytest fixture, `make_storage_credential_spn`, in `fixtures.py` to
simplify writing tests requiring Databricks Storage Credentials with
Azure Service Principal auth. Addition of a new test file for the Azure
integration of the project, including new classes, methods, and test
cases for testing the migration of Azure Service Principals to UC
Storage Credentials. These improvements will ensure better security and
management of storage access using Azure Service Principals, while
providing more efficient and robust testing capabilities.
* Added permission migration support for feature tables and the root
permissions for models and feature tables
([#997](#997)). This commit
introduces support for migration of permissions related to feature
tables and sets root permissions for models and feature tables. New
functions such as `feature_store_listing`, `feature_tables_root_page`,
`models_root_page`, and `tokens_and_passwords` have been added to
facilitate population of a workspace access page with necessary
permissions information. The `factory` function in `manager.py` has been
updated to include new listings for models' root page, feature tables'
root page, and the feature store for enhanced management and access
control of models and feature tables. New classes and methods have been
implemented to handle permissions for these resources, utilizing
`GenericPermissionsSupport`, `AccessControlRequest`, and `MigratedGroup`
classes. Additionally, new test methods have been included to verify
feature tables listing functionality and root page listing functionality
for feature tables and registered models. The test manager method has
been updated to include `feature-tables` in the list of items to be
checked for permissions, ensuring comprehensive testing of permission
functionality related to these new feature tables.
* Added support for serving endpoints
([#990](#990)). In this
release, we have made significant enhancements to support serving
endpoints in our open-source library. The `fixtures.py` file in the
`databricks.labs.ucx.mixins` module has been updated with new classes
and functions to create and manage serving endpoints, accompanied by
integration tests to verify their functionality. We have added a new
listing for serving endpoints in the assessment's permissions crawling,
using the `ws.serving_endpoints.list` function and the
`serving-endpoints` category. A new integration test, "test_endpoints,"
has been added to verify that assessments now crawl permissions for
serving endpoints. This test demonstrates the ability to migrate
permissions from one group to another. The test suite has been updated
to ensure the proper functioning of the new feature and improve the
assessment of permissions for serving endpoints, ensuring compatibility
with the updated `test_manager.py` file.
* Expanded end-user documentation with detailed descriptions for
workflows and commands
([#999](#999)). The
Databricks Labs UCX project has been updated with several new features
to assist in upgrading to Unity Catalog, including an assessment
workflow that generates a detailed compatibility report for workspace
entities, a group migration workflow for upgrading all Databricks
workspace assets, and utility commands for managing cross-workspace
installations. The Assessment Report now includes a more detailed
summary of the assessment findings, table counts, database summaries,
and external locations. Additional improvements include expanded
workspace group migration to handle potential conflicts with locally
scoped group names, enhanced documentation for external Hive Metastore
integration, a new debugging notebook, and detailed descriptions of
table upgrade considerations, data access permissions, external storage,
and table crawler.
* Fixed `config.yml` upgrade from very old versions
([#984](#984)). In this
release, we've introduced enhancements to the configuration upgrading
process for `config.yml` in our open-source library. We've replaced the
previous `v1_migrate` class method with a new implementation that
specifically handles migration from version 1. The new method retrieves
the `groups` field, extracts the `selected` value, and assigns it to the
`include_group_names` key in the configuration. The
`backup_group_prefix` value from the `groups` field is assigned to the
`renamed_group_prefix` key, and the `groups` field is removed, with the
version number updated to 2. These changes simplify the code and improve
readability, enabling users to upgrade smoothly from version 1 of the
configuration. Furthermore, we've added new unit tests to the
`test_config.py` file to ensure backward compatibility. Two new tests,
`test_v1_migrate_zeroconf` and `test_v1_migrate_some_conf`, have been
added, utilizing the `MockInstallation` class and loading the
configuration using `WorkspaceConfig`. These tests enhance the
robustness and reliability of the migration process for `config.yml`.
* Renamed columns in assessment SQL queries to use actual names, not
aliases ([#983](#983)). In
this update, we have resolved an issue where aliases used for column
references in SQL queries caused errors in certain setups by renaming
them to use actual names. Specifically, for assessment SQL queries, we
have modified the definition of the `is_delta` column to use the actual
`table_format` name instead of the alias `format`. This change improves
compatibility and enhances the reliability of query execution. As a
software engineer, you will appreciate that this modification ensures
consistent interpretation of column references across various setups,
thereby avoiding potential errors caused by aliases. This change does
not introduce any new methods, but instead modifies existing
functionality to use actual column names, ensuring a more reliable and
consistent SQL query for the `05_0_all_tables` assessment.
* Updated groups permissions validation to use Table ACL cluster
([#979](#979)). In this
update, the `validate_groups_permissions` task has been modified to
utilize the Table ACL cluster, as indicated by the inclusion of
`job_cluster="tacl"`. This task is responsible for ensuring that all
crawled permissions are accurately applied to the destination groups by
calling the `permission_manager.apply_group_permissions` method during
the migration state. This modification enhances the validation of group
permissions by performing it on the Table ACL cluster, potentially
improving performance or functionality. If you are implementing this
project, it is crucial to comprehend the consequences of this change on
your permissions validation process and adjust your workflows
appropriately.

Update databricks-labs-blueprint requirement from ~=0.2.4 to ~=0.3.0 (#1001)

Updates the requirements on
[databricks-labs-blueprint](https://github.com/databrickslabs/blueprint)
to permit the latest version.
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/databrickslabs/blueprint/releases">databricks-labs-blueprint's
releases</a>.</em></p>
<blockquote>
<h2>v0.3.0</h2>
<ul>
<li>Added automated upgrade framework (<a
href="https://redirect.github.com/databrickslabs/blueprint/issues/50">#50</a>).
This update introduces an automated upgrade framework for managing and
applying upgrades to the product, with a new <code>upgrades.py</code>
file that includes a <code>ProductInfo</code> class having methods for
version handling, wheel building, and exception handling. The test code
organization has been improved, and new test cases, functions, and a
directory structure for fixtures and unit tests have been added for the
upgrades functionality. The <code>test_wheels.py</code> file now checks
the version of the Databricks SDK and handles cases where the version
marker is missing or does not contain the <code>__version__</code>
variable. Additionally, a new <code>Application State Migrations</code>
section has been added to the README, explaining the process of seamless
upgrades from version X to version Z through version Y, addressing the
need for configuration or database state migrations as the application
evolves. Users can apply these upgrades by following an idiomatic usage
pattern involving several classes and functions. Furthermore,
improvements have been made to the <code>_trim_leading_whitespace</code>
function in the <code>commands.py</code> file of the
<code>databricks.labs.blueprint</code> module, ensuring accurate and
consistent removal of leading whitespace for each line in the command
string, leading to better overall functionality and
maintainability.</li>
<li>Added brute-forcing <code>SerdeError</code> with
<code>as_dict()</code> and <code>from_dict()</code> (<a
href="https://redirect.github.com/databrickslabs/blueprint/issues/58">#58</a>).
This commit introduces a brute-forcing approach for handling
<code>SerdeError</code> using <code>as_dict()</code> and
<code>from_dict()</code> methods in an open-source library. The new
<code>SomePolicy</code> class demonstrates the usage of these methods
for manual serialization and deserialization of custom classes. The
<code>as_dict()</code> method returns a dictionary representation of the
class instance, and the <code>from_dict()</code> method, decorated with
<code>@classmethod</code>, creates a new instance from the provided
dictionary. Additionally, the GitHub Actions workflow for acceptance
tests has been updated to include the <code>ready_for_review</code>
event type, ensuring that tests run not only for opened and synchronized
pull requests but also when marked as &quot;ready for review.&quot;
These changes provide developers with more control over the
deserialization process and facilitate debugging in cases where default
deserialization fails, but should be used judiciously to avoid brittle
code.</li>
<li>Fixed nightly integration tests run as service principals (<a
href="https://redirect.github.com/databrickslabs/blueprint/issues/52">#52</a>).
In this release, we have enhanced the compatibility of our codebase with
service principals, particularly in the context of nightly integration
tests. The <code>Installation</code> class in the
<code>databricks.labs.blueprint.installation</code> module has been
refactored, deprecating the <code>current</code> method and introducing
two new methods: <code>assume_global</code> and
<code>assume_user_home</code>. These methods enable users to install and
manage <code>blueprint</code> as either a global or user-specific
installation. Additionally, the <code>existing</code> method has been
updated to work with the new <code>Installation</code> methods. In the
test suite, the <code>test_installation.py</code> file has been updated
to correctly detect global and user-specific installations when running
as a service principal. These changes improve the testability and
functionality of our software, ensuring seamless operation with service
principals during nightly integration tests.</li>
<li>Made <code>test_existing_installations_are_detected</code> more
resilient (<a
href="https://redirect.github.com/databrickslabs/blueprint/issues/51">#51</a>).
In this release, we have added a new test function
<code>test_existing_installations_are_detected</code> that checks if
existing installations are correctly detected and retries the test for
up to 15 seconds if they are not. This improves the reliability of the
test by making it more resilient to potential intermittent failures. We
have also added an import from <code>databricks.sdk.retries</code> named
<code>retried</code> which is used to retry the test function in case of
an <code>AssertionError</code>. Additionally, the test function
<code>test_existing</code> has been renamed to
<code>test_existing_installations_are_detected</code> and the
<code>xfail</code> marker has been removed. We have also renamed the
test function <code>test_dataclass</code> to
<code>test_loading_dataclass_from_installation</code> for better
clarity. This change will help ensure that the library is correctly
detecting existing installations and improve the overall quality of the
codebase.</li>

<h2>0.3.0</h2>
<ul>
<li>Added automated upgrade framework (<a
href="https://redirect.github.com/databrickslabs/blueprint/issues/50">#50</a>).
This update introduces an automated upgrade framework for managing and
applying upgrades to the product, with a new <code>upgrades.py</code>
file that includes a <code>ProductInfo</code> class having methods for
version handling, wheel building, and exception handling. The test code
organization has been improved, and new test cases, functions, and a
directory structure for fixtures and unit tests have been added for the
upgrades functionality. The <code>test_wheels.py</code> file now checks
the version of the Databricks SDK and handles cases where the version
marker is missing or does not contain the <code>__version__</code>
variable. Additionally, a new <code>Application State Migrations</code>
section has been added to the README, explaining the process of seamless
upgrades from version X to version Z through version Y, addressing the
need for configuration or database state migrations as the application
evolves. Users can apply these upgrades by following an idiomatic usage
pattern involving several classes and functions. Furthermore,
improvements have been made to the <code>_trim_leading_whitespace</code>
function in the <code>commands.py</code> file of the
<code>databricks.labs.blueprint</code> module, ensuring accurate and
consistent removal of leading whitespace for each line in the command
string, leading to better overall functionality and
maintainability.</li>
<li>Added brute-forcing <code>SerdeError</code> with
<code>as_dict()</code> and <code>from_dict()</code> (<a
href="https://redirect.github.com/databrickslabs/blueprint/issues/58">#58</a>).
This commit introduces a brute-forcing approach for handling
<code>SerdeError</code> using <code>as_dict()</code> and
<code>from_dict()</code> methods in an open-source library. The new
<code>SomePolicy</code> class demonstrates the usage of these methods
for manual serialization and deserialization of custom classes. The
<code>as_dict()</code> method returns a dictionary representation of the
class instance, and the <code>from_dict()</code> method, decorated with
<code>@classmethod</code>, creates a new instance from the provided
dictionary. Additionally, the GitHub Actions workflow for acceptance
tests has been updated to include the <code>ready_for_review</code>
event type, ensuring that tests run not only for opened and synchronized
pull requests but also when marked as &quot;ready for review.&quot;
These changes provide developers with more control over the
deserialization process and facilitate debugging in cases where default
deserialization fails, but should be used judiciously to avoid brittle
code.</li>
<li>Fixed nightly integration tests run as service principals (<a
href="https://redirect.github.com/databrickslabs/blueprint/issues/52">#52</a>).
In this release, we have enhanced the compatibility of our codebase with
service principals, particularly in the context of nightly integration
tests. The <code>Installation</code> class in the
<code>databricks.labs.blueprint.installation</code> module has been
refactored, deprecating the <code>current</code> method and introducing
two new methods: <code>assume_global</code> and
<code>assume_user_home</code>. These methods enable users to install and
manage <code>blueprint</code> as either a global or user-specific
installation. Additionally, the <code>existing</code> method has been
updated to work with the new <code>Installation</code> methods. In the
test suite, the <code>test_installation.py</code> file has been updated
to correctly detect global and user-specific installations when running
as a service principal. These changes improve the testability and
functionality of our software, ensuring seamless operation with service
principals during nightly integration tests.</li>
<li>Made <code>test_existing_installations_are_detected</code> more
resilient (<a
href="https://redirect.github.com/databrickslabs/blueprint/issues/51">#51</a>).
In this release, we have added a new test function
<code>test_existing_installations_are_detected</code> that checks if
existing installations are correctly detected and retries the test for
up to 15 seconds if they are not. This improves the reliability of the
test by making it more resilient to potential intermittent failures. We
have also added an import from <code>databricks.sdk.retries</code> named
<code>retried</code> which is used to retry the test function in case of
an <code>AssertionError</code>. Additionally, the test function
<code>test_existing</code> has been renamed to
<code>test_existing_installations_are_detected</code> and the
<code>xfail</code> marker has been removed. We have also renamed the
test function <code>test_dataclass</code> to
<code>test_loading_dataclass_from_installation</code> for better
clarity. This change will help ensure that the library is correctly
detecting existing installations and improve the overall quality of the
codebase.</li>

Create UC external locations in Azure based on migrated storage credentials (#992)

Handle widget delete on upgrade platform bug (#1011)
nfx added a commit that referenced this pull request Mar 7, 2024
* Added AWS S3 support for `migrate-locations` command ([#1009](#1009)). In this release, the open-source library has been enhanced with AWS S3 support for the `migrate-locations` command, enabling efficient and secure management of S3 data. The new functionality includes the identification of missing S3 prefixes and the creation of corresponding roles and policies through the addition of methods `_identify_missing_paths`, `_get_existing_credentials_dict`, and `create_external_locations`. The library now also includes new classes `AwsIamRole`, `ExternalLocationInfo`, and `StorageCredentialInfo` for better handling of AWS-related functionality. Additionally, two new tests, `test_create_external_locations` and `test_create_external_locations_skip_existing`, have been added to ensure the correct behavior of the new AWS-related functionality. The new test function `test_migrate_locations_aws` checks the AWS-specific implementation of the `migrate-locations` command, while `test_missing_aws_cli` verifies the correct error message is displayed when the AWS CLI is not found in the system path. These changes enhance the library's capabilities, improving data security, privacy, and overall performance for users working with AWS S3.
* Added `databricks labs ucx create-uber-principal` command to create Azure Service Principal for migration ([#976](#976)). The new CLI command, `databricks labs ucx create-uber-principal`, has been introduced to create an Azure Service Principal (SPN) and grant it STORAGE BLOB READER access on all the storage accounts used by the tables in the workspace. The SPN information is then stored in the UCX cluster policy. A new class, AzureApiClient, has been added to isolate Azure API calls, and unit and integration tests have been included to verify the functionality. This development enhances migration capabilities for Azure workspaces, providing a more streamlined and automated way to create and manage Service Principals, and improves the functionality and usability of the UCX tool. The changes are well-documented and follow the project's coding standards.
* Added `migrate-locations` command ([#1016](#1016)). In this release, we've added a new CLI command, `migrate_locations`, to create Unity Catalog (UC) external locations. This command extracts candidates for location creation from the `guess_external_locations` assessment task and checks if corresponding UC Storage Credentials exist before creating the locations. Currently, the command only supports Azure, with plans to add support for AWS and GCP in the future. The `migrate_locations` function is marked with the `ucx.command` decorator and is available as a command-line interface (CLI) command. The pull request also includes unit tests for this new command, which check the environment (Azure, AWS, or GCP) before executing the migration and log a message if the environment is AWS or GCP, indicating that the migration is not yet supported on those platforms. No changes have been made to existing workflows, commands, or tables.
* Added handling for widget delete on upgrade platform bug ([#1011](#1011)). In this release, the `_install_dashboard` method in `dashboards.py` has been updated to handle a platform bug that occurred during the deletion of dashboard widgets during an upgrade process (issue [#1011](#1011)). Previously, the method attempted to delete each widget using the `self._ws.dashboard_widgets.delete(widget.id)` command, which resulted in a `TypeError` when attempting to delete a widget. The updated method now includes a try/except block that catches this `TypeError` and logs a warning message, while also tracking the issue under bug ES-1061370. The rest of the method remains unchanged, creating a dashboard with the given name, role, and parent folder ID if no widgets are present. This enhancement improves the robustness of the `_install_dashboard` method by adding error handling for the SDK API response when deleting dashboard widgets, ensuring a smoother upgrade process.
* Create UC external locations in Azure based on migrated storage credentials ([#992](#992)). The `locations.py` file in the `databricks.labs.ucx.azure` package has been updated to include a new class `ExternalLocationsMigration`, which creates UC external locations in Azure based on migrated storage credentials. This class takes various arguments, including `WorkspaceClient`, `HiveMetastoreLocations`, `AzureResourcePermissions`, and `AzureResources`. It has a `run()` method that lists any missing external locations in UC, extracts their location URLs, and attempts to create a UC external location with a mapped storage credential name if the missing external location is in the mapping. The class also includes helper methods for generating credential name mappings. Additionally, the `resources.py` file in the same package has been modified to include a new method `managed_identity_client_id`, which retrieves the client ID of a managed identity associated with a given access connector. Test functions for the `ExternalLocationsMigration` class and Azure external locations functionality have been added in the new file `test_locations.py`. The `test_resources.py` file has been updated to include tests for the `managed_identity_client_id` method. A new `mappings.json` file has also been added for tests related to Azure external location mappings based on migrated storage credentials.
* Deprecate legacy installer ([#1014](#1014)). In this release, we have deprecated the legacy installer for the UCX project, which was previously implemented as a bash script. A warning message has been added to inform users about the deprecation and direct them to the UCX installation instructions. The functionality of the script remains unchanged, and it still performs tasks such as installing Python dependencies and building Python bindings. The script will eventually be replaced with the `databricks labs install ucx` command. This change is part of issue [#1014](#1014) and is intended to streamline the installation process and improve the overall user experience. We recommend that users update their installation process to the new recommended method as soon as possible to avoid any issues with the legacy installer in the future.
* Prompt user if Terraform utilised for deploying infrastructure ([#1004](#1004)). In this update, the `config.py` file has been modified to include a new attribute, `is_terraform_used`, in the `WorkspaceConfig` class. This boolean flag indicates whether Terraform has been used for deploying certain entities in the workspace. Issue [#393](#393) has been addressed with this change. The `WorkspaceInstaller` configuration has also been updated to take advantage of this new attribute, allowing developers to determine if Terraform was used for infrastructure deployment, thereby increasing visibility into the deployment process. Additionally, a new prompt has been added to the `warehouse_type` function to ascertain if Terraform is being utilized for infrastructure deployment, setting the `is_terraform_used` variable to True if it is. This improvement is intended for software engineers adopting this open-source library.
* Updated CONTRIBUTING.md ([#1005](#1005)). In this contribution to the open-source library, the CONTRIBUTING.md file has been significantly updated with clearer instructions on how to effectively contibute to the project. The previous command to print the Python path has been removed, as the IDE is now advised to be configured to use the Python interpreter from the virtual environment. A new step has been added, recommending the use of a consistent styleguide and formatting of the code before every commit. Moreover, it is now encouraged to run tests before committing to minimize potential issues during the review process. The steps on how to make a Fork from the ucx repo and create a PR have been updated with links to official documentation. Lastly, the commit now includes information on handling dependency errors that may occur after `git pull`.
* Updated databricks-labs-blueprint requirement from ~=0.2.4 to ~=0.3.0 ([#1001](#1001)). In this pull request update, the requirements file, pyproject.toml, has been modified to upgrade the databricks-labs-blueprint package from version ~0.2.4 to ~0.3.0. This update integrates the latest features and bug fixes of the package, including an automated upgrade framework, a brute-forcing approach for handling SerdeError, and enhancements for running nightly integration tests with service principals. These improvements increase the testability and functionality of the software, ensuring its stable operation with service principals during nightly integration tests. Furthermore, the reliability of the test for detecting existing installations has been reinforced by adding a new test function that checks for the correct detection of existing installations and retries the test for up to 15 seconds if they are not.

of a managed identity associated with a given access connector. Test
functions for the `ExternalLocationsMigration` class and Azure external
locations functionality have been added in the new file
`test_locations.py`. The `test_resources.py` file has been updated to
include tests for the `managed_identity_client_id` method. A new
`mappings.json` file has also been added for tests related to Azure
external location mappings based on migrated storage credentials.
* Deprecate legacy installer
([#1014](#1014)). In this
release, we have deprecated the legacy installer for the UCX project,
which was previously implemented as a bash script. A warning message has
been added to inform users about the deprecation and direct them to the
UCX installation instructions. The functionality of the script remains
unchanged, and it still performs tasks such as installing Python
dependencies and building Python bindings. The script will eventually be
replaced with the `databricks labs install ucx` command. This change is
part of issue [#1014](#1014)
and is intended to streamline the installation process and improve the
overall user experience. We recommend that users update their
installation process to the new recommended method as soon as possible
to avoid any issues with the legacy installer in the future.
* Prompt user if Terraform utilised for deploying infrastructure
([#1004](#1004)). In this
update, the `config.py` file has been modified to include a new
attribute, `is_terraform_used`, in the `WorkspaceConfig` class. This
boolean flag indicates whether Terraform has been used for deploying
certain entities in the workspace. Issue
[#393](#393) has been
addressed with this change. The `WorkspaceInstaller` configuration has
also been updated to take advantage of this new attribute, allowing
developers to determine if Terraform was used for infrastructure
deployment, thereby increasing visibility into the deployment process.
Additionally, a new prompt has been added to the `warehouse_type`
function to ascertain if Terraform is being utilized for infrastructure
deployment, setting the `is_terraform_used` variable to True if it is.
This improvement is intended for software engineers adopting this
open-source library.
* Updated CONTRIBUTING.md
([#1005](#1005)). In this
contribution to the open-source library, the CONTRIBUTING.md file has
been significantly updated with clearer instructions on how to
effectively contibute to the project. The previous command to print the
Python path has been removed, as the IDE is now advised to be configured
to use the Python interpreter from the virtual environment. A new step
has been added, recommending the use of a consistent styleguide and
formatting of the code before every commit. Moreover, it is now
encouraged to run tests before committing to minimize potential issues
during the review process. The steps on how to make a Fork from the ucx
repo and create a PR have been updated with links to official
documentation. Lastly, the commit now includes information on handling
dependency errors that may occur after `git pull`.
* Updated databricks-labs-blueprint requirement from ~=0.2.4 to ~=0.3.0
([#1001](#1001)). In this
pull request update, the requirements file, pyproject.toml, has been
modified to upgrade the databricks-labs-blueprint package from version
~0.2.4 to ~0.3.0. This update integrates the latest features and bug
fixes of the package, including an automated upgrade framework, a
brute-forcing approach for handling SerdeError, and enhancements for
running nightly integration tests with service principals. These
improvements increase the testability and functionality of the software,
ensuring its stable operation with service principals during nightly
integration tests. Furthermore, the reliability of the test for
detecting existing installations has been reinforced by adding a new
test function that checks for the correct detection of existing
installations and retries the test for up to 15 seconds if they are not.

Dependency updates:

* Updated databricks-labs-blueprint requirement from ~=0.2.4 to ~=0.3.0

Added group members difference to the output of `validate-groups-membership` cli command (#995)

The `validate-groups-membership` command has been updated to include a
comparison of group memberships at both the account and workspace
levels, displaying the difference in members between the two levels in a
new column. This enhancement allows for a more detailed analysis of
group memberships, with the added functionality implemented in the
`validate_group_membership` function in the `groups.py` file located in
the `databricks/labs/ucx/workspace_access` directory. A new output
field, "group\_members\_difference," has been added to represent the
difference in the number of members between a workspace group and an
associated account group. The corresponding unit test file,
"test\_groups.py," has been updated to include a new test case that
verifies the calculation of the "group\_members\_difference" value. This
change provides users with a more comprehensive view of their group
memberships and allows them to easily identify any discrepancies between
the account and workspace levels. The functionality of the other
commands remains unchanged.

Improved installation integration test flakiness (#998)

- improved `_infer_error_from_job_run` and `_infer_error_from_task_run`
to also catch `KeyError` and `ValueError`
- removed retries for `Unknown` errors for installation tests

Expanded end-user documentation with detailed descriptions for workflows and commands (#999)

The Databricks Labs UCX project has been updated with several new
features to assist in upgrading to Unity Catalog. These include various
workflows and command-line utilities, such as an assessment workflow
that generates a detailed compatibility report for workspace entities
and a group migration workflow to upgrade all Databricks workspace
assets. Additionally, new utility commands have been added for managing
cross-workspace installations, and users can now view deployed
workflows' status and repair failed workflows. A new end-user
documentation has also been introduced, featuring comprehensive
descriptions of workflows, commands, and an assessment report image. The
Assessment Report, generated from UCX tools, now includes a more
detailed summary of the assessment findings, table counts, database
summaries, and external locations. Improved documentation for external
Hive Metastore integration and a new debugging notebook are also
included in this release. Lastly, the workspace group migration feature
has been expanded to handle potential conflicts when migrating multiple
workspaces with locally scoped group names.

Release v0.14.0 (#1000)

* Added `upgraded_from_workspace_id` property to migrated tables to
indicated the source workspace
([#987](#987)). In this
release, updates have been made to the `_migrate_external_table`,
`_migrate_dbfs_root_table`, and `_migrate_view` methods in the
`table_migrate.py` file to include a new parameter `upgraded_from_ws` in
the SQL commands used to alter tables, views, or managed tables. This
parameter is used to store the source workspace ID in the migrated
tables, indicating the migration origin. A new utility method
`sql_alter_from` has been added to the `Table` class in `tables.py` to
generate the SQL command with the new parameter. Additionally, a new
class-level attribute `UPGRADED_FROM_WS_PARAM` has been added to the
`Table` class in `tables.py` to indicate the source workspace. A new
property `upgraded_from_workspace_id` has been added to migrated tables
to store the source workspace ID. These changes resolve issue
[#899](#899) and are tested
through manual testing, unit tests, and integration tests. No new CLI
commands, workflows, or tables have been added or modified, and there
are no changes to user documentation.
* Added a command to create account level groups if they do not exist
([#763](#763)). This commit
introduces a new feature that enables the creation of account-level
groups if they do not already exist in the account. A new command,
`create-account-groups`, has been added to the `databricks labs ucx`
tool, which crawls all workspaces in the account and creates
account-level groups if a corresponding workspace-local group is not
found. The feature supports various scenarios, including creating
account-level groups that exist in some workspaces but not in others,
and creating multiple account-level groups with the same name but
different members. Several new methods have been added to the
`account.py` file to support the new feature, and the `test_account.py`
file has been updated with new tests to ensure the correct behavior of
the `create_account_level_groups` method. Additionally, the `cli.py`
file has been updated to include the new `create-account-groups`
command. With these changes, users can easily manage account-level
groups and ensure that they are consistent across all workspaces in the
account, improving the overall user experience.
* Added assessment for the incompatible `RunSubmit` API usages
([#849](#849)). In this
release, the assessment functionality for incompatible `RunSubmit` API
usages has been significantly enhanced through various changes. The
'clusters.py' file has seen improvements in clarity and consistency with
the renaming of private methods `check_spark_conf` to
`_check_spark_conf` and `check_cluster_failures` to
`_check_cluster_failures`. The `_assess_clusters` method has been
updated to call the renamed `_check_cluster_failures` method for
thorough checks of cluster configurations, resulting in better
assessment functionality. A new `SubmitRunsCrawler` class has been added
to the `databricks.labs.ucx.assessment.jobs` module, implementing
`CrawlerBase`, `JobsMixin`, and `CheckClusterMixin` classes. This class
crawls and assesses job runs based on their submitted runs, ensuring
compatibility and identifying failure issues. Additionally, a new
configuration attribute, `num_days_submit_runs_history`, has been
introduced in the `WorkspaceConfig` class of the `config.py` module,
controlling the number of days for which submission history of
`RunSubmit` API calls is retained. Lastly, various new JSON files have
been added for unit testing, assessing the `RunSubmit` API usages
related to different scenarios like dbt task runs, Git source-based job
runs, JAR file runs, and more. These tests will aid in identifying and
addressing potential compatibility issues with the `RunSubmit` API.
* Added group members difference to the output of
`validate-groups-membership` cli command
([#995](#995)). The
`validate-groups-membership` command has been updated to include a
comparison of group memberships at both the account and workspace
levels. This enhancement is implemented through the
`validate_group_membership` function, which has been updated to
calculate the difference in members between the two levels and display
it in a new `group_members_difference` column. This allows for a more
detailed analysis of group memberships and easily identifies any
discrepancies between the account and workspace levels. The
corresponding unit test file, "test_groups.py," has been updated to
include a new test case that verifies the calculation of the
`group_members_difference` value. The functionality of the other
commands remains unchanged. The new `group_members_difference` value is
calculated as the difference in the number of members in the workspace
group and the account group, with a positive value indicating more
members in the workspace group and a negative value indicating more
members in the account group. The table template in the labs.yml file
has also been updated to include the new column for the group membership
difference.
* Added handling for empty `directory_id` if managed identity
encountered during the crawling of StoragePermissionMapping
([#986](#986)). This PR adds
a `type` field to the `StoragePermissionMapping` and `Principal`
dataclasses to differentiate between service principals and managed
identities, allowing `None` for the `directory_id` field if the
principal is not a service principal. During the migration to UC storage
credentials, managed identities are currently ignored. These changes
improve handling of managed identities during the crawling of
`StoragePermissionMapping`, prevent errors when creating storage
credentials with managed identities, and address issue
[#339](#339). The changes
are tested through unit tests, manual testing, and integration tests,
and only affect the `StoragePermissionMapping` class and related
methods, without introducing new commands, workflows, or tables.
* Added migration for Azure Service Principals with secrets stored in
Databricks Secret to UC Storage Credentials
([#874](#874)). In this
release, we have made significant updates to migrate Azure Service
Principals with their secrets stored in Databricks Secret to UC Storage
Credentials, enhancing security and management of storage access. The
changes include: Addition of a new `migrate_credentials` command in the
`labs.yml` file to migrate credentials for storage access to UC storage
credential. Modification of `secrets.py` to handle the case where a
secret has been removed from the backend and to log warning messages for
secrets with invalid Base64 bytes. Introduction of the
`StorageCredentialManager` and `ServicePrincipalMigration` classes in
`credentials.py` to manage Azure Service Principals and their associated
client secrets, and to migrate them to UC Storage Credentials. Addition
of a new `directory_id` attribute in the `Principal` class and its
associated dataclass in `resources.py` to store the directory ID for
creating UC storage credentials using a service principal. Creation of a
new pytest fixture, `make_storage_credential_spn`, in `fixtures.py` to
simplify writing tests requiring Databricks Storage Credentials with
Azure Service Principal auth. Addition of a new test file for the Azure
integration of the project, including new classes, methods, and test
cases for testing the migration of Azure Service Principals to UC
Storage Credentials. These improvements will ensure better security and
management of storage access using Azure Service Principals, while
providing more efficient and robust testing capabilities.
* Added permission migration support for feature tables and the root
permissions for models and feature tables
([#997](#997)). This commit
introduces support for migration of permissions related to feature
tables and sets root permissions for models and feature tables. New
functions such as `feature_store_listing`, `feature_tables_root_page`,
`models_root_page`, and `tokens_and_passwords` have been added to
facilitate population of a workspace access page with necessary
permissions information. The `factory` function in `manager.py` has been
updated to include new listings for models' root page, feature tables'
root page, and the feature store for enhanced management and access
control of models and feature tables. New classes and methods have been
implemented to handle permissions for these resources, utilizing
`GenericPermissionsSupport`, `AccessControlRequest`, and `MigratedGroup`
classes. Additionally, new test methods have been included to verify
feature tables listing functionality and root page listing functionality
for feature tables and registered models. The test manager method has
been updated to include `feature-tables` in the list of items to be
checked for permissions, ensuring comprehensive testing of permission
functionality related to these new feature tables.
* Added support for serving endpoints
([#990](#990)). In this
release, we have made significant enhancements to support serving
endpoints in our open-source library. The `fixtures.py` file in the
`databricks.labs.ucx.mixins` module has been updated with new classes
and functions to create and manage serving endpoints, accompanied by
integration tests to verify their functionality. We have added a new
listing for serving endpoints in the assessment's permissions crawling,
using the `ws.serving_endpoints.list` function and the
`serving-endpoints` category. A new integration test, "test_endpoints,"
has been added to verify that assessments now crawl permissions for
serving endpoints. This test demonstrates the ability to migrate
permissions from one group to another. The test suite has been updated
to ensure the proper functioning of the new feature and improve the
assessment of permissions for serving endpoints, ensuring compatibility
with the updated `test_manager.py` file.
* Expanded end-user documentation with detailed descriptions for
workflows and commands
([#999](#999)). The
Databricks Labs UCX project has been updated with several new features
to assist in upgrading to Unity Catalog, including an assessment
workflow that generates a detailed compatibility report for workspace
entities, a group migration workflow for upgrading all Databricks
workspace assets, and utility commands for managing cross-workspace
installations. The Assessment Report now includes a more detailed
summary of the assessment findings, table counts, database summaries,
and external locations. Additional improvements include expanded
workspace group migration to handle potential conflicts with locally
scoped group names, enhanced documentation for external Hive Metastore
integration, a new debugging notebook, and detailed descriptions of
table upgrade considerations, data access permissions, external storage,
and table crawler.
* Fixed `config.yml` upgrade from very old versions
([#984](#984)). In this
release, we've introduced enhancements to the configuration upgrading
process for `config.yml` in our open-source library. We've replaced the
previous `v1_migrate` class method with a new implementation that
specifically handles migration from version 1. The new method retrieves
the `groups` field, extracts the `selected` value, and assigns it to the
`include_group_names` key in the configuration. The
`backup_group_prefix` value from the `groups` field is assigned to the
`renamed_group_prefix` key, and the `groups` field is removed, with the
version number updated to 2. These changes simplify the code and improve
readability, enabling users to upgrade smoothly from version 1 of the
configuration. Furthermore, we've added new unit tests to the
`test_config.py` file to ensure backward compatibility. Two new tests,
`test_v1_migrate_zeroconf` and `test_v1_migrate_some_conf`, have been
added, utilizing the `MockInstallation` class and loading the
configuration using `WorkspaceConfig`. These tests enhance the
robustness and reliability of the migration process for `config.yml`.
* Renamed columns in assessment SQL queries to use actual names, not
aliases ([#983](#983)). In
this update, we have resolved an issue where aliases used for column
references in SQL queries caused errors in certain setups by renaming
them to use actual names. Specifically, for assessment SQL queries, we
have modified the definition of the `is_delta` column to use the actual
`table_format` name instead of the alias `format`. This change improves
compatibility and enhances the reliability of query execution. As a
software engineer, you will appreciate that this modification ensures
consistent interpretation of column references across various setups,
thereby avoiding potential errors caused by aliases. This change does
not introduce any new methods, but instead modifies existing
functionality to use actual column names, ensuring a more reliable and
consistent SQL query for the `05_0_all_tables` assessment.
* Updated groups permissions validation to use Table ACL cluster
([#979](#979)). In this
update, the `validate_groups_permissions` task has been modified to
utilize the Table ACL cluster, as indicated by the inclusion of
`job_cluster="tacl"`. This task is responsible for ensuring that all
crawled permissions are accurately applied to the destination groups by
calling the `permission_manager.apply_group_permissions` method during
the migration state. This modification enhances the validation of group
permissions by performing it on the Table ACL cluster, potentially
improving performance or functionality. If you are implementing this
project, it is crucial to comprehend the consequences of this change on
your permissions validation process and adjust your workflows
appropriately.

Added AWS S3 support for `migrate-locations` command (#1009)

Release v0.15.0 (#1020)

* Added AWS S3 support for `migrate-locations` command
([#1009](#1009)). In this
release, the open-source library has been enhanced with AWS S3 support
for the `migrate-locations` command, enabling efficient and secure
management of S3 data. The new functionality includes the identification
of missing S3 prefixes and the creation of corresponding roles and
policies through the addition of methods `_identify_missing_paths`,
`_get_existing_credentials_dict`, and `create_external_locations`. The
library now also includes new classes `AwsIamRole`,
`ExternalLocationInfo`, and `StorageCredentialInfo` for better handling
of AWS-related functionality. Additionally, two new tests,
`test_create_external_locations` and
`test_create_external_locations_skip_existing`, have been added to
ensure the correct behavior of the new AWS-related functionality. The
new test function `test_migrate_locations_aws` checks the AWS-specific
implementation of the `migrate-locations` command, while
`test_missing_aws_cli` verifies the correct error message is displayed
when the AWS CLI is not found in the system path. These changes enhance
the library's capabilities, improving data security, privacy, and
overall performance for users working with AWS S3.
* Added `databricks labs ucx create-uber-principal` command to create
Azure Service Principal for migration
([#976](#976)). The new CLI
command, `databricks labs ucx create-uber-principal`, has been
introduced to create an Azure Service Principal (SPN) and grant it
STORAGE BLOB READER access on all the storage accounts used by the
tables in the workspace. The SPN information is then stored in the UCX
cluster policy. A new class, AzureApiClient, has been added to isolate
Azure API calls, and unit and integration tests have been included to
verify the functionality. This development enhances migration
capabilities for Azure workspaces, providing a more streamlined and
automated way to create and manage Service Principals, and improves the
functionality and usability of the UCX tool. The changes are
well-documented and follow the project's coding standards.
* Added `migrate-locations` command
([#1016](#1016)). In this
release, we've added a new CLI command, `migrate_locations`, to create
Unity Catalog (UC) external locations. This command extracts candidates
for location creation from the `guess_external_locations` assessment
task and checks if corresponding UC Storage Credentials exist before
creating the locations. Currently, the command only supports Azure, with
plans to add support for AWS and GCP in the future. The
`migrate_locations` function is marked with the `ucx.command` decorator
and is available as a command-line interface (CLI) command. The pull
request also includes unit tests for this new command, which check the
environment (Azure, AWS, or GCP) before executing the migration and log
a message if the environment is AWS or GCP, indicating that the
migration is not yet supported on those platforms. No changes have been
made to existing workflows, commands, or tables.
* Added handling for widget delete on upgrade platform bug
([#1011](#1011)). In this
release, the `_install_dashboard` method in `dashboards.py` has been
updated to handle a platform bug that occurred during the deletion of
dashboard widgets during an upgrade process (issue
[#1011](#1011)). Previously,
the method attempted to delete each widget using the
`self._ws.dashboard_widgets.delete(widget.id)` command, which resulted
in a `TypeError` when attempting to delete a widget. The updated method
now includes a try/except block that catches this `TypeError` and logs a
warning message, while also tracking the issue under bug ES-1061370. The
rest of the method remains unchanged, creating a dashboard with the
given name, role, and parent folder ID if no widgets are present. This
enhancement improves the robustness of the `_install_dashboard` method
by adding error handling for the SDK API response when deleting
dashboard widgets, ensuring a smoother upgrade process.
* Create UC external locations in Azure based on migrated storage
credentials ([#992](#992)).
The `locations.py` file in the `databricks.labs.ucx.azure` package has
been updated to include a new class `ExternalLocationsMigration`, which
creates UC external locations in Azure based on migrated storage
credentials. This class takes various arguments, including
`WorkspaceClient`, `HiveMetastoreLocations`, `AzureResourcePermissions`,
and `AzureResources`. It has a `run()` method that lists any missing
external locations in UC, extracts their location URLs, and attempts to
create a UC external location with a mapped storage credential name if
the missing external location is in the mapping. The class also includes
helper methods for generating credential name mappings. Additionally,
the `resources.py` file in the same package has been modified to include
a new method `managed_identity_client_id`, which retrieves the client ID
of a managed identity associated with a given access connector. Test
functions for the `ExternalLocationsMigration` class and Azure external
locations functionality have been added in the new file
`test_locations.py`. The `test_resources.py` file has been updated to
include tests for the `managed_identity_client_id` method. A new
`mappings.json` file has also been added for tests related to Azure
external location mappings based on migrated storage credentials.
* Deprecate legacy installer
([#1014](#1014)). In this
release, we have deprecated the legacy installer for the UCX project,
which was previously implemented as a bash script. A warning message has
been added to inform users about the deprecation and direct them to the
UCX installation instructions. The functionality of the script remains
unchanged, and it still performs tasks such as installing Python
dependencies and building Python bindings. The script will eventually be
replaced with the `databricks labs install ucx` command. This change is
part of issue [#1014](#1014)
and is intended to streamline the installation process and improve the
overall user experience. We recommend that users update their
installation process to the new recommended method as soon as possible
to avoid any issues with the legacy installer in the future.
* Prompt user if Terraform utilised for deploying infrastructure
([#1004](#1004)). In this
update, the `config.py` file has been modified to include a new
attribute, `is_terraform_used`, in the `WorkspaceConfig` class. This
boolean flag indicates whether Terraform has been used for deploying
certain entities in the workspace. Issue
[#393](#393) has been
addressed with this change. The `WorkspaceInstaller` configuration has
also been updated to take advantage of this new attribute, allowing
developers to determine if Terraform was used for infrastructure
deployment, thereby increasing visibility into the deployment process.
Additionally, a new prompt has been added to the `warehouse_type`
function to ascertain if Terraform is being utilized for infrastructure
deployment, setting the `is_terraform_used` variable to True if it is.
This improvement is intended for software engineers adopting this
open-source library.
* Updated CONTRIBUTING.md
([#1005](#1005)). In this
contribution to the open-source library, the CONTRIBUTING.md file has
been significantly updated with clearer instructions on how to
effectively contibute to the project. The previous command to print the
Python path has been removed, as the IDE is now advised to be configured
to use the Python interpreter from the virtual environment. A new step
has been added, recommending the use of a consistent styleguide and
formatting of the code before every commit. Moreover, it is now
encouraged to run tests before committing to minimize potential issues
during the review process. The steps on how to make a Fork from the ucx
repo and create a PR have been updated with links to official
documentation. Lastly, the commit now includes information on handling
dependency errors that may occur after `git pull`.
* Updated databricks-labs-blueprint requirement from ~=0.2.4 to ~=0.3.0
([#1001](#1001)). In this
pull request update, the requirements file, pyproject.toml, has been
modified to upgrade the databricks-labs-blueprint package from version
~0.2.4 to ~0.3.0. This update integrates the latest features and bug
fixes of the package, including an automated upgrade framework, a
brute-forcing approach for handling SerdeError, and enhancements for
running nightly integration tests with service principals. These
improvements increase the testability and functionality of the software,
ensuring its stable operation with service principals during nightly
integration tests. Furthermore, the reliability of the test for
detecting existing installations has been reinforced by adding a new
test function that checks for the correct detection of existing
installations and retries the test for up to 15 seconds if they are not.

…pal` command (#993)

## Changes
Added CLI command `databricks labs ucx create-uber-principal` for
creating uber-IAM profile for performing external table migration on
AWS.

Logic:
* Stop if UCX migration cluster policy is not found
* Collect paths of all locations/paths used in tables (call
`external_location.snapshot`)
* If cluster policy has an existing iam instance profile/role specified,
then add/update migration policy providing access to the locations
* If cluster policy does not have iam instance profile/role specified,
then create new iam profile/role and migration policy, and add it to the
cluster policy

* Added AWS S3 support for `migrate-locations` command
([#1009](#1009)). In this
release, the open-source library has been enhanced with AWS S3 support
for the `migrate-locations` command, enabling efficient and secure
management of S3 data. The new functionality includes the identification
of missing S3 prefixes and the creation of corresponding roles and
policies through the addition of methods `_identify_missing_paths`,
`_get_existing_credentials_dict`, and `create_external_locations`. The
library now also includes new classes `AwsIamRole`,
`ExternalLocationInfo`, and `StorageCredentialInfo` for better handling
of AWS-related functionality. Additionally, two new tests,
`test_create_external_locations` and
`test_create_external_locations_skip_existing`, have been added to
ensure the correct behavior of the new AWS-related functionality. The
new test function `test_migrate_locations_aws` checks the AWS-specific
implementation of the `migrate-locations` command, while
`test_missing_aws_cli` verifies the correct error message is displayed
when the AWS CLI is not found in the system path. These changes enhance
the library's capabilities, improving data security, privacy, and
overall performance for users working with AWS S3.
* Added `databricks labs ucx create-uber-principal` command to create
Azure Service Principal for migration
([#976](#976)). The new CLI
command, `databricks labs ucx create-uber-principal`, has been
introduced to create an Azure Service Principal (SPN) and grant it
STORAGE BLOB READER access on all the storage accounts used by the
tables in the workspace. The SPN information is then stored in the UCX
cluster policy. A new class, AzureApiClient, has been added to isolate
Azure API calls, and unit and integration tests have been included to
verify the functionality. This development enhances migration
capabilities for Azure workspaces, providing a more streamlined and
automated way to create and manage Service Principals, and improves the
functionality and usability of the UCX tool. The changes are
well-documented and follow the project's coding standards.
* Added `migrate-locations` command
([#1016](#1016)). In this
release, we've added a new CLI command, `migrate_locations`, to create
Unity Catalog (UC) external locations. This command extracts candidates
for location creation from the `guess_external_locations` assessment
task and checks if corresponding UC Storage Credentials exist before
creating the locations. Currently, the command only supports Azure, with
plans to add support for AWS and GCP in the future. The
`migrate_locations` function is marked with the `ucx.command` decorator
and is available as a command-line interface (CLI) command. The pull
request also includes unit tests for this new command, which check the
environment (Azure, AWS, or GCP) before executing the migration and log
a message if the environment is AWS or GCP, indicating that the
migration is not yet supported on those platforms. No changes have been
made to existing workflows, commands, or tables.
* Added handling for widget delete on upgrade platform bug
([#1011](#1011)). In this
release, the `_install_dashboard` method in `dashboards.py` has been
updated to handle a platform bug that occurred during the deletion of
dashboard widgets during an upgrade process (issue
[#1011](#1011)). Previously,
the method attempted to delete each widget using the
`self._ws.dashboard_widgets.delete(widget.id)` command, which resulted
in a `TypeError` when attempting to delete a widget. The updated method
now includes a try/except block that catches this `TypeError` and logs a
warning message, while also tracking the issue under bug ES-1061370. The
rest of the method remains unchanged, creating a dashboard with the
given name, role, and parent folder ID if no widgets are present. This
enhancement improves the robustness of the `_install_dashboard` method
by adding error handling for the SDK API response when deleting
dashboard widgets, ensuring a smoother upgrade process.
* Create UC external locations in Azure based on migrated storage
credentials ([#992](#992)).
The `locations.py` file in the `databricks.labs.ucx.azure` package has
been updated to include a new class `ExternalLocationsMigration`, which
creates UC external locations in Azure based on migrated storage
credentials. This class takes various arguments, including
`WorkspaceClient`, `HiveMetastoreLocations`, `AzureResourcePermissions`,
and `AzureResources`. It has a `run()` method that lists any missing
external locations in UC, extracts their location URLs, and attempts to
create a UC external location with a mapped storage credential name if
the missing external location is in the mapping. The class also includes
helper methods for generating credential name mappings. Additionally,
the `resources.py` file in the same package has been modified to include
a new method `managed_identity_client_id`, which retrieves the client ID
of a managed identity associated with a given access connector. Test
functions for the `ExternalLocationsMigration` class and Azure external
locations functionality have been added in the new file
`test_locations.py`. The `test_resources.py` file has been updated to
include tests for the `managed_identity_client_id` method. A new
`mappings.json` file has also been added for tests related to Azure
external location mappings based on migrated storage credentials.
* Deprecate legacy installer
([#1014](#1014)). In this
release, we have deprecated the legacy installer for the UCX project,
which was previously implemented as a bash script. A warning message has
been added to inform users about the deprecation and direct them to the
UCX installation instructions. The functionality of the script remains
unchanged, and it still performs tasks such as installing Python
dependencies and building Python bindings. The script will eventually be
replaced with the `databricks labs install ucx` command. This change is
part of issue [#1014](#1014)
and is intended to streamline the installation process and improve the
overall user experience. We recommend that users update their
installation process to the new recommended method as soon as possible
to avoid any issues with the legacy installer in the future.
* Prompt user if Terraform utilised for deploying infrastructure
([#1004](#1004)). In this
update, the `config.py` file has been modified to include a new

also been updated to take advantage of this new attribute, allowing

function to ascertain if Terraform is being utilized for infrastructure
deployment, setting the `is_terraform_used` variable to True if it is.
