Subject [jira] [Commented] (YARN-2136) RMStateStore can explicitly handle store/update events when fenced
Date Tue, 05 Aug 2014 12:36:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-2136?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14086204#comment-14086204
] 

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

While closing RMStateStore, we will first drain the event queue in the dispatcher. So, there
may be some store/update events sitting in the queue, which will be completed first.

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