Sean Busbey commented on YARN-3774:
-----------------------------------

Please make sure to document the impact of moving to Curator 3. The last time 
we updated the curator version (2.6.0 -> 2.7.1) they broke compatibility.

> ZKRMStateStore should use Curator 3.0 and avail CuratorOp

> YARN-2716 changes ZKRMStateStore to use Curator. Transactions added there are 
> somewhat involved, and could be improved using CuratorOp introduced in 
> Curator 3.0. Hadoop 3.0.0 would be a good time to upgrade the Curator version 
> and make this change.
