Todd Lipcon updated HDFS-1467:
------------------------------
Attachment: hdfs-1467-fixed.txt
Take two!
The issue was that we actually _depended_ on BlockReceiver to mutate the block
object. But, we want to use the original block object when passing on the
request to the next node in the pipeline. This version just saves off the Block
at the top of the function to a copy, and uses that for the downstream pipeline
node.
TestReplication and TestPipelines both pass with this new version of the patch.
I'm going to run all the tests just to be safe this time :)
