Subject [jira] [Commented] (YARN-2136) RMStateStore can explicitly handle store/update events when fenced
Date Thu, 14 Aug 2014 19:14:14 GMT

    [ https://issues.apache.org/jira/browse/YARN-2136?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14097402#comment-14097402
] 

Varun Saxena commented on YARN-2136:
------------------------------------

Yes, completely agree with you [~jianhe]. dispatcher.stop() will cause events in dispatcher
queue(if any) to be processed first. These events would be lost if we call closeInternal()
before dispatcher.stop()

> RMStateStore can choose to handle/ignore store/update events upfront instead of invoking
more ZK operations if state store is at fenced state.
