Karthik Kambatla commented on YARN-1068:
----------------------------------------

Per discussion on YARN-1309 and YARN-142, looks like we should throw 
YarnException and not IOException. However, the actual exceptions to be thrown 
are defined in HAServiceProtocol which doesn't have YarnException listed.

So, I guess we will have to leave the RMHAProtocolService as is.
