Aaron T. Myers updated HDFS-1575:
---------------------------------
Attachment: hdfs-1575-22.0.patch
What's attached is a faithful back-port of the trunk commit. In the course of
doing this back-port I identified a bug, which I've filed under HDFS-1964.
Let's commit this patch to branch-0.22 and then I'll back-port the bug fix.
