[jira] [Commented] (YARN-4277) containers would be leaked if nm crashed and rm failover

    [ https://issues.apache.org/jira/browse/YARN-4277?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14984585#comment-14984585 ] 

sandflee commented on YARN-4277:
--------------------------------

Is there any plan to store NM info?  [~jlowe] [~djp] [~jianhe],  we could just store NM info not containers running on NM.
Without NM info, 
1,  containers could be leaked as in  this issue. 
2,  AM knows nothing if nm crashed forever and RM failover
