Subject [jira] [Commented] (YARN-2136) RMStateStore can explicitly handle store/update events when fenced
Date Thu, 14 Aug 2014 20:24:19 GMT

    [ https://issues.apache.org/jira/browse/YARN-2136?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14097582#comment-14097582
] 

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

Ideally these events should be processed. But if Store is already fenced, I guess NoAuthException
will again be reported by ZK, so processing this event wont lead to any useful operation.

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