Karthik Kambatla commented on YARN-1222:
----------------------------------------
While working on fencing aspects of ZKRMStateStore, I feel it might be cleaner
to have a helper inner class ZKOps that handles connections to ZooKeeper and
the create/delete/set operations.

> Using multi-operations for every ZK interaction.
> In every operation, automatically creating/deleting a lock znode that is the
