Subject [jira] Updated: (HDFS-1400) HDFS federation: Introduced block pool ID into DataTransferProtocol
Date Tue, 14 Sep 2010 21:01:34 GMT

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.
