Subject [jira] [Commented] (YARN-998) Keep NM resource updated through dynamic resource config for RM/NM restart
Date Sat, 02 Apr 2016 00:19:25 GMT

    [ https://issues.apache.org/jira/browse/YARN-998?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15222587#comment-15222587

Kuhu Shukla commented on YARN-998:
----------------------------------

bq. shall we consider to move it inside of rm.registerNode()?
bq. that's nice idea . we can do I think..I'm +1 on that.

I was of the understanding that {{drainEvents}} would also address cases when nodes are refreshed,
shutdown and basically get any event in the dispatcher queue out. Wouldn't moving it under
registerNode alone break that? Please let me know what am I missing here. Thanks!

> When NM is restarted by plan or from a failure, previous dynamic resource setting should
be kept for consistency.
