Subject [jira] [Commented] (YARN-998) Keep NM resource updated through dynamic resource config for RM/NM restart
Date Tue, 29 Mar 2016 14:07:25 GMT

    [ https://issues.apache.org/jira/browse/YARN-998?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15216051#comment-15216051

Junping Du commented on YARN-998:
---------------------------------

Thanks [~brahmareddy] to follow up on this test failure. I tried to run the test on my local
machine which didn't fail so I thought it is related to test env as get failed intermittently.
If adding {{rm.drainEvents()}} can help here, shall we consider to move it inside of rm.registerNode()?
So that we don't have to call rm.drainEvent() after registerNode() like we what do in TestResourceTrackerService().
Anyway, I will file a separated JIRA to address this.

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