Karthik Kambatla updated YARN-1029:
-----------------------------------

New patch: EmbeddedElectorService fails if the data in the znode is incorrect, instead of
blindly clearing it.

> It should be possible to embed common ActiveStandyElector into the RM such that ZooKeeper
based leader election and notification is in-built. In conjunction with a ZK state store,
this configuration will be a simple deployment option.
