Suresh Srinivas updated HDFS-1400:
----------------------------------
Attachment: HDFS-1400.patch
First version of the patch with DataTransferProtocol changes. Since the change
to use block pool ID is not complete, there are a lot of TODO:FEDERATION
comments identifying further changes that are required.
In tests TestDataTransferProtocol and TestBlockReplacement, there were
instances where DatanodeTransfer protocol helper methods were not used to send
requests. Instead the test serialized and wrote individual elements of the
protocol request. I have changed this to use helper methods. This helps in
catching the future protocol changes as compile time error instead of runtime.
