Purpose of this PR

Use controller-runtime to reconsturct spark operator.

Close #547
Close #507
Close #2052

Proposed changes

Spark Operator Executable

Split the operator into two separate components i.e. controller and webhook.

Use cobra to implement spark-operator command, and it has two sub commands controller and webhook, one can start controller/webhook by spark-operator controller start and spark-operator webhook start repectively.

$ make build-operator
$ bin/spark-operator --help          
Spark operator

Usage:
  spark-operator [flags]
  spark-operator [command]

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  controller  Spark operator controller
  help        Help about any command
  version     Print version information
  webhook     Spark operator webhook

Flags:
  -h, --help   help for spark-operator

Use "spark-operator [command] --help" for more information about a command.

SparkApplication/ScheduledSparkController controller only watches resources in the spark job namespaces.
Add finalizer for SparkApplication to ensure all sub resources e.g. pods, services, ingress related to that app will be deleted when deleting the SparkApplication.

Helm Chart

Change imagePullSecrets to image.pullSecrets.
All controller configurations are prefixed with controller e.g. controller.replicaCount and controller.resyncInterval
All webhook configurations are prefixed with webhook e.g. webhook.replicaCount and `webhook.failurePolicy.
All monitoring configurations are prefixed with promethues e.g. promethues.metrics and promethues.podMonitor.
Enable leader election for controller/webhook by default to ensure only an controller instance is working when upgrading the chart.
The update strategy of controller/webhook deployment will be the rolling update, not recreate.
Deploy webhook server with a separated deployment and enable webhook server by default.
The webhook secret will not be created and updated by operator, and the certificates will not change during chart upgrading/rollback process.
Change the default of webhook timeoutSeconds from 30 to 10.
Change the default of webhook failurePolicy from Ignore to Fail.
Change the default spark job namespace from [] to ["default], thus the SparkApplication under examples directory can be running directly without creating rbac resources manually.
Service account are configured with controller.serviceAccount, webhook.serviceAccount and spark.serviceAccount respectively.
RBAC resources are configured with controller.rbac, webhook.rbac and spark.rbac respectively.
logLevel will be one of info, debug and error.

Thanks @ChenYi015 for this major refactoring! One of the referenced issues was created by a former colleague of mine 5 years ago. Glad to see finally someone take a stab at it. Given the sheer size of the changes, more eyes are needed for the review. We can use help from fellow community members. Tagging some of them here @bnetzi @peter-mcclonski @jacobsalway but anyone is welcome to comment

Happy to take a look but is there a natural way we could split this PR to make it easier to review?

api/v1beta1/scheduledsparkapplication_types.go

Apart from the static code review, given the major refactoring, we need to ensure all tests pass. I am not certain about our current test coverage, but we should create a new image and test it locally if reviewers have the bandwidth. This would ensure it works with common examples without errors.

We could create a pre-release tagged as 2.0 to include other improvements as well. This will give users time to migrate to the newer version since it introduces breaking changes.

api/v1beta1/sparkapplication_types.go

api/v1beta2/sparkapplication_types.go

Not directly connected to this PR but it's probably a good idea to get some end to end tests running in CI since they're currently disabled

Let me explain what I had did. First, I use kubebuilder to scaffold the project.

mkdir spark-operator
cd spark-operator
kubebuilder init --domain sparkoperator.k8s.io --repo github.com/kubeflow/spark-operator

Then, create new API version as follows:

$ # Create v1beta1 version (create resource only)
$ kubebuilder create api --version v1beta1 --kind SparkApplication
INFO Create Resource [y/n] y
INFO Create Controller [y/n] n
$ kubebuilder create api --version v1beta1 --kind ScheduledSparkApplication
INFO Create Resource [y/n] y
INFO Create Controller [y/n] n

$ # Create v1beta2 version (create both resource and controller)
$ kubebuilder create api --version v1beta2 --kind SparkApplication
INFO Create Resource [y/n] y
INFO Create Controller [y/n] y
$ kubebuilder create api --version v1beta2 --kind ScheduledSparkApplication
INFO Create Resource [y/n] y
INFO Create Controller [y/n] y

The structure of the project is like this:

$ tree -L 1
.
├── Dockerfile
├── Makefile
├── PROJECT       # Kubebuilder use PROJECT file to hold project matadata and scaffold the project.
├── README.md
├── api
├── bin
├── cmd
├── config
├── go.mod
├── go.sum
├── hack
├── internal
└── test

Then I move the orignal API definitions from pkg/apis/v1beta1 to api/v1beta1 and pkgs/apis/v1beta2 to api/v1beta2 respectivelyls. After modifying the API definition, we can use make manifests to generate CustomResourceDefinitions to config/crd/bases directory.

ChenYi015 · 2024-07-02T02:12:51Z

We will define controllers for SparkApplication, ScheduledSparkApplication, MutaingWebhookConfiguration and ValidatingWebhokConfiguration. The controller for webhook configurations are used to patch generated CA certificates when a new mutating/validating webhook created/updated.

$ tree -d internal/controller
internal/controller
├── mutatingwebhookconfiguration
├── scheduledsparkapplication
├── sparkapplication
└── validatingwebhookconfiguration

For every controller, we need to define event filter (predicate), event handler and reconciler, for detailed information, refer Architecture Concept Diagram.

We will define webhooks for SparkApplication, ScheduledSparkApplication and Spark Pod:

internal/webhook
├── doc.go
├── scheduledsparkapplication_defaulter.go
├── scheduledsparkapplication_validator.go
├── sparkapplication_defaulter.go
├── sparkapplication_validator.go
├── sparkpod_defaulter.go
├── sparkpod_defaulter_test.go
├── suite_test.go
└── webhook.go

For the webhook for SparkApplication and ScheduledSparkApplication, a defaulter/validator is defined to default/validate it.
For the webhook for Spark pods, a defaulter is defined to patch fileds like volumes, volumesMounts and envs to driver/executor pods.

ChenYi015 · 2024-07-02T02:30:55Z

I had did some tests as follows (go, docker, make are needed):

# Build operator image, create a kind cluster and load image to the kind cluster
make docker-build kind-create-cluster kind-load-image

Install the chart:

helm install spark-operator charts/spark-operator-chart \
    --namespace spark-operator \
    --create-namespace

Submit an example spark-pi sparkapplication and wait it to be completed:

kubectl apply -f examples/spark-pi.yaml

Check out controller logs:

$ kubectl logs -n spark-operator spark-operator-controller-fc5bd5bbc-4mzp4
...

I am not certain about our current test coverage, but we should create a new image and test it locally if reviewers have the bandwidth. This would ensure it works with common examples without errors.

@vara-bonthu Now we can use make unit-test to see the test coverage:

To test the operator and helm chart with kind cluster, just do as follows:

make docker-build kind-create-cluster kind-load-image

kind binary will be downloaded automatically to bin directory.

/hold for review

yuchaoran2011 · 2024-07-03T05:22:53Z

We could create a pre-release tagged as 2.0 to include other improvements as well. This will give users time to migrate to the newer version since it introduces breaking changes.

I second @vara-bonthu's suggestion here. Given that this PR has completely reworked the implementation, it makes sense to mark it as the start of v2.0. And we can create a new branch for it and merge it there

ChenYi015 · 2024-07-03T08:11:05Z

@yuchaoran2011 Maybe we can make a new branch named release-2.0 as described in #1975.

ChenYi015 · 2024-07-23T07:15:24Z

@yuchaoran2011 I had did some benchmarks to compare start latency (created state -> submitted state) between helm chart v1.4.5 and this one. Install the operator with 30 worker threads and webhook enabled, using 20 cpu cores and 16 Gi memory. Then submit 1000 spark-pi application concurrently. For chart v1.4.5, the average start latency is 3m53s, and the controller-runtime version is 3m35s, just a little bit faster. Maybe we can achieve better performance by tuning controller-runtime related parameters.

Now that #2089 is merged, this one is good to merge as well. Excited to see we officially kick off 2.0!

@ChenYi015 Hello!
Can you tell me how to use livenessProbe and other probes in helm values?

ChenYi015 · 2024-09-23T12:07:01Z

@ChenYi015 Hello! Can you tell me how to use livenessProbe and other probes in helm values?

@Viktor3434 For now, livenessProbe and readinessProbe are enabled by default and cannot be configured via helm values. I am wondering why do you want it to be configurable?

Viktor3434 · 2024-09-23T12:49:13Z

@ChenYi015 Thanks, can you tell me if probes have been added for the SparkApplication resource?

jacobsalway · 2024-09-23T12:52:27Z

@Viktor3434 do you mean probes on the Spark driver and executor pods? If so, can you go into more detail on the reason for wanting to?

Viktor3434 · 2024-09-24T06:24:05Z

@jacobsalway Hi! sorry for the long wait for a reply
I am not very familiar with spark concepts.

We have a SparkApplication that reads data from kafka and writes it to greenplum.
Relatively recently there was a case where the application got stuck, perhaps probes could help, but I'm not sure.

jacobsalway · 2024-09-24T06:41:42Z

@Viktor3434 no problem. Spark itself doesn't have a healthcheck port that you could configure a probe for. I would suggest you scrape metrics from the driver and set up separate alerting and monitoring based on streaming progress, Kafka consumer group lag or other metrics that could give you a proxy on whether the job is progressing or stuck.

If you'd like, you can start a thread in the community Slack and tag me so we can discuss in more detail.
