Suresh Srinivas commented on HADOOP-7972:
-----------------------------------------
We should have used DFSClient in FailoverController when accessing
HAServiceProtocol. I am not sure I agree that unwrapping in a Helper is such an
ugly choice.
Any way, this could be moved over to translators when we move over
HAServiceProtocol to protobuf.
