[jira] [Commented] (YARN-1121) RMStateStore should flush all pending store events before closing

    [ https://issues.apache.org/jira/browse/YARN-1121?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13801409#comment-13801409 ] 

Omkar Vinit Joshi commented on YARN-1121:
-----------------------------------------

[~bikassaha] we have a single dispatcher queue. so should we ignore other events when RM is going down and selectively only process rm state store writes related events? In any case we will have very short time before we actually get kill -9.
