Robert Chansler updated HADOOP-3283:
------------------------------------
Release Note:
Added an IPC server in DataNode and a new IPC protocol InterDatanodeProtocol. Added conf properties dfs.datanode.ipc.address and dfs.datanode.handler.count with defaults "0.0.0.0:50020" and 3, respectively.
Changed the serialization in DatanodeRegistration and DatanodeInfo, and therefore, updated the versionID in ClientProtocol, DatanodeProtocol, NamenodeProtocol.
