Subject [jira] [Commented] (YARN-3039) [Collector wireup] Implement timeline app-level collector service discovery
Date Thu, 08 Sep 2016 22:58:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-3039?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15475278#comment-15475278

Li Lu commented on YARN-3039:

Just noticed the following discussion when looking into HA support for timeline v2:
bq Given it may needs more treatment for state preserving, shall we spin off the related code
change and defer it to a later jira? I think it shouldn't block our next milestone.

Seems like we have yet to open a follow up JIRA to track the state preserving work. I'll open
a new one and add it to YARN-5355.

off-node clients to send writes to the right ATS writer. This should also handle the case
of AM failures.
