Aaron T. Myers commented on HADOOP-7972:
----------------------------------------
bq. We should have used DFSClient in FailoverController when accessing
HAServiceProtocol.
Not sure I agree with that. DFSClient currently only accesses ClientProtocol
methods, and it seems a bit odd to lump in the HA administrative API into
DFSClient.
bq. I am not sure I agree that unwrapping in a Helper is such an ugly choice.
I don't think it's necessarily ugly, just not as beautiful as it could be. :)
Such a class as I described it could also be used for HAServiceProtocol
instantiation, which is currently duplicated in both HAAdmin and MiniDFSCluster.
bq. Any way, this could be moved over to translators when we move over
HAServiceProtocol to protobuf.
Sure, that's a fine solution.
