Subject [jira] [Commented] (YARN-2375) Allow enabling/disabling timeline server per framework
Date Tue, 18 Nov 2014 23:30:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2375?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14217049#comment-14217049
] 

Zhijie Shen commented on YARN-2375:
-----------------------------------

bq. Do you mean that we should not check for TIMELINE_SERVICE_ENABLED flag in the Application
Master and rather have it work same way that it was doing before and only check that flag
while sending data to timeline server?

I think the logic could be: when TIMELINE_SERVICE_ENABLED == true, read the domain env var
and construct the timeline client. Only if the timeline client is not null, the AM will send
the data to timeline server where it should do it.

> This JIRA is to remove the ats enabled flag check within the TimelineClientImpl. Example
where this fails is below.
