Description

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.

Curator is considering shading guava through CURATOR-200. In Hadoop 3, we should upgrade to the next Curator version.
