Eli Collins updated HDFS-2654:
------------------------------
Attachment: hdfs-2654-b1-2.patch
Updated patch for branch-1, right one this time. And the previous comment
should have referred to comment #3, the branch-1 patch just needs the comment.
> Make BlockReaderLocal not extend RemoteBlockReader2

> The BlockReaderLocal code paths are easier to understand (especially true on
> branch-1 where BlockReaderLocal inherits code from BlockerReader and
> FSInputChecker) if the local and remote block reader implementations are
> independent, and they're not really sharing much code anyway. If for some
> reason they start to share sifnificant code we can make the BlockReader
> interface an abstract class.
