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?
