Subject [jira] [Updated] (YARN-2375) Allow enabling/disabling timeline server per framework
Date Thu, 20 Nov 2014 15:28:34 GMT

     [ https://issues.apache.org/jira/browse/YARN-2375?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Mit Desai updated YARN-2375:
    Attachment: YARN-2375.patch

Thanks for taking a look [~zjshen] and [~jeagles].
Attaching updated patch to address Zhijie's comments.

# In ApplicationMaster.finish(), we now stop the timeline client if the timelineClient instance
is not null.
# Fixed the indent issue in TimelineClientImpl#serviceInit().
# LOG.info("Timeline server is (not) enabled") changed to LOG.info("Timeline service is (not)
enabled"); to be consistent with the log statements in other places.

I still have not added the test case for testing the scenario if MAPREDUCE_JOB_EMIT_TIMELINE_DATA
= true and TIMELINE_SERVICE_ENABLED = false; MiniMRYarnCluster doesn't start the timeline

MiniMRYarnCluster seems to follow a little different path for starting up the timeline service.
I am investigating that currently. I propose to address that in a followup jira. That way
we can have the important fix checked in.
If you guys are ok with that, I will file a jira.
