Subject [jira] [Commented] (YARN-2136) RMStateStore can explicitly handle store/update events when fenced
Date Thu, 14 Aug 2014 17:42:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-2136?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14097266#comment-14097266
] 

Jian He commented on YARN-2136:
-------------------------------

bq. Hence dispatcher queue draining shouldn't matter as ZKClient is already closed.
After checking the code, I think we should flip the order "closeInternal()" and "dispatcher.stop();"
 right?
{code}
  protected void serviceStop() throws Exception {
    closeInternal();
    dispatcher.stop();
  }
{code}

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