Apache BookKeeper Tutorial Implemented with Scala #165

bwsw · 2017-05-26T08:07:52Z

Hello, guys. Our developer reimplemented your tutorial with Scala. May be you find it interesting to expand your documentation. Just FYI it is here: https://github.com/bwsw/bookkeeper-tutorial-scala

eolivelli · 2017-05-26T08:21:27Z

@bwsw awesome !
Thank you for sharing you work!

sijie · 2017-05-26T15:04:38Z

@bwsw great job!

@eolivelli do you want to update the documentation to include @bwsw 's tutorial?

eolivelli · 2017-05-26T15:07:14Z

@sijie I will do as soon as possible

eolivelli · 2017-05-26T15:12:10Z

@sijie
we can add a link to the project here http://bookkeeper.apache.org/docs/master/bookkeeperTutorial.html
after the reference to @ivankelly repository https://github.com/ivankelly/bookkeeper-tutorial/
is it OK ?
shall we create a JIRA for this ?

sijie · 2017-05-26T15:26:35Z

@eolivelli let's discuss the issue tracking at the mail-list. but my thought here is - if there is a github issue here, we don't need to create a jira. but the pull request need to be "Issue-<Issue-#>: ...."

eolivelli · 2017-05-26T20:12:18Z

@sijie committed to staging website, see https://issues.apache.org/jira/browse/BOOKKEEPER-1080

sijie · 2017-05-26T20:19:06Z

oh I just realized that site repo is still in svn. we might need to move that to git (and probably rewrite this using static generator like jeklly). Otherwise there is visibility on the changes on the site.

For this change, +1 for the staging.

eolivelli · 2017-05-27T07:36:33Z

Done
I cannot close this issue, @bwsw can you close it?

sijie · 2017-05-27T08:37:51Z

@eolivelli I believe we might need to request permission from INFRA team.

Sorry for being naive on this subject. What is the real use of implementing tutorial in Scala? and have a separate git repo for it?

sijie · 2017-06-01T17:53:28Z

@jvrao

re "a separate git repo" - current java tutorial is a tutorial wrote by @ivankelly , it is not in bookkeeper's repo.

a tutorial is just a sample application to show how to use BookKeeper to build applications. I don't know if it is necessary to have it along with the main repo. If it is easier, we can merge them into the main repo.

scala vs java - my take is just different ways to use bookkeeper in different languages.

Descriptions of the changes in this PR: Fix checkstyle error in core module Author: Arvin <arvindevel@gmail.com> Reviewers: Sijie Guo <sijie@apache.org> This closes apache#192 from ArvinDevel/enable_check, closes apache#165

### Motivation The auditor didn't close the ledger manager and ledger under replication manager the thread will leak. Run the test `AuditorPeriodicBookieCheckTest` and get the stack. ## Before this PR: ``` Full thread dump Java HotSpot(TM) 64-Bit Server VM (11.0.15+8-LTS-149 mixed mode): Threads class SMR info: _java_thread_list=0x0000600003e44460, length=16, elements={ 0x00007fad34009000, 0x00007fad45032800, 0x00007fad14813800, 0x00007fad44010800, 0x00007fad44011800, 0x00007fad45037800, 0x00007fad3400a000, 0x00007fad45812800, 0x00007fad34944000, 0x00007fad4585f800, 0x00007fad45456000, 0x00007fad4444c000, 0x00007fad3431b800, 0x00007face5825800, 0x00007face5860800, 0x00007face4009800 } "main" #1 prio=5 os_prio=31 cpu=1801.68ms elapsed=20.85s tid=0x00007fad34009000 nid=0x2a03 waiting on condition [0x000000030a10d000] java.lang.Thread.State: TIMED_WAITING (parking) at jdk.internal.misc.Unsafe.park(java.base@11.0.15/Native Method) -
