Sriram Rao updated HADOOP-4697:
-------------------------------
Attachment: patch.4697
A patch that fixes the issue is attached.
No new test is included: this bug was found with a Hadoop+KFS deployment; it
was tested in that deployment and verified. Verifying this issue requires a
Hadoop+KFS deployment and this is done elsewhere.
