Subject [jira] [Commented] (YARN-4234) New put APIs in TimelineClient for ats v1.5
Date Wed, 09 Dec 2015 03:58:11 GMT

    [ https://issues.apache.org/jira/browse/YARN-4234?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15047987#comment-15047987
] 

Li Lu commented on YARN-4234:
-----------------------------

Patch generally LGTM. The only issue is that if NameNode is unavailable and retry is not set,
the timeline client will quickly retry and then fail. This will cause either application attempts
to fail, or the RM to fail to start. Maybe we can try some mechanisms like in FileSystemRMStateStore#startInternal,
where we explicitly change related retry policy config? 

Other than this corner case issue I'm fine with this patch. Right now people are reaching
agreements on YARN-3623, so probably YARN-3623 can go in very soon. This said, could some
committers please review the current patch? Thanks!
