Subject [jira] [Commented] (YARN-353) Add Zookeeper-based store implementation for RMStateStore
Date Thu, 18 Jul 2013 17:24:56 GMT

    [ https://issues.apache.org/jira/browse/YARN-353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13712523#comment-13712523
] 

Bikas Saha commented on YARN-353:
---------------------------------

bq. ZKRMStateStore#getNewZooKeeper need not be synchronized
bq. fixed
The code is derived from ActiveStandyLeaderElector code in hadoop common. It was synchronized
there for a race condition that showed up in testing. I would like to keep the synchronization
as it was in the original patch.

bq. the patch still seems to have NUM_RETRIES
Why should NUM_RETRIES not be there?
