[jira] [Commented] (YARN-2834) Resource manager crashed with Null
Pointer Exception
[ https://issues.apache.org/jira/browse/YARN-2834?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14273129#comment-14273129 ]
Karthik Kambatla commented on YARN-2834:
----------------------------------------
Sorry for missing this earlier, doesn't this undo YARN-2010? If I am not mistaken, the RM will crash if it fails to recover apps now. [~jianhe] - thoughts?
