Subject [jira] [Commented] (YARN-1121) RMStateStore should flush all pending store events before closing
Date Sat, 09 Nov 2013 00:51:17 GMT

    [ https://issues.apache.org/jira/browse/YARN-1121?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13817908#comment-13817908

Vinod Kumar Vavilapalli commented on YARN-1121:
-----------------------------------------------

Looks good overall. Checking this in.

One thing of note is that you are removing locking for service-life-cycle methods in RMStateStore.
I verified that it seems fine - events coming in during serviceStop are ignored due to draining
and other blocking calls are okay to happen.
