Karthik Kambatla updated YARN-1029:
-----------------------------------
Attachment: yarn-1029-6.patch
The new patch uses RMFatalEvent for both elector and store fatal events - the
RM transitions to active if the store is fenced, shuts down otherwise.
Deployed on a 2-node cluster and verified failover while running an example
job.
> Allow embedding leader election into the RM

> conjunction with a ZK state store, this configuration will be a simple
> deployment option.
