Bikas Saha commented on YARN-1029:
----------------------------------
Thanks for addressing the comments. I was expecting
RMStateStoreOperationFailedEvent to be replaced by the new RMFatalErrorEvent
just like the Embedded elector event got replaced. Not much use in the store
sending an event to the RM and then the RM sending an event to itself again,
right?
> Allow embedding leader election into the RM

> 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.
