Subject [jira] [Commented] (YARN-6377) NMTimelinePublisher#serviceStop does not stop timeline clients
Date Fri, 31 Mar 2017 06:19:42 GMT

    [ https://issues.apache.org/jira/browse/YARN-6377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15950391#comment-15950391

Vrushali C commented on YARN-6377:
----------------------------------

Patch looks fine.

Not in the scope of this jira, but wondering about the RM timeline connections. We have the
TimelineServiceV2Publisher posting application and container lifecycle events for the RM and
I see a stopTimelineCollector on PUBLISH_APPLICATION_FINISHED_ENTITY. I am looking through
the code and trying to recollect as well, do we have any timeline service related stop on
the RM side?

> While discussing YARN-6342, Varun found another issue regarding TimelineV2Client. "In
NMTimelinePublisher#serviceStop though we are not explicitly stopping app related timeline
clients. I think should be done."
