Tsz Wo (Nicholas), SZE commented on HDFS-892:
---------------------------------------------
Patch looks mostly good. Some comments:
- It looks like that all the changes are compatible changes except renaming
register(..) to registerDatanode(..) in DatanodeProtocol. So the protocol
version have to be updated.
- Do we need a versionID for the new NamenodeProtocols?
> optionally use Avro for namenode RPC
