Suresh Srinivas commented on HDFS-2518:
---------------------------------------
bq. GetBlockKeysRequestProto, GetTransactionIdRequestProto,
EndCheckpointResponseProto are empty, can we replace them with a single empty
proto?
bq. Instead of StartCheckpointResponseProto, can we just use
NamenodeCommandProto which is already defined? That applies to many response
protos e.g. RegisterResponseProto could be replaced with
NamenodeRegistrationProto.
The reason is, the request and response could in the future change to include
additional optional fields.
