Todd Lipcon updated HDFS-1141:
------------------------------

    Attachment: hdfs-1141.txt

Here's a patch with just those test cases that apply to this bug from HDFS-1139.

Note: this does change the exception text coming out of completeFile to be more specific - now it actually contains "Lease mismatch" or "File is closed", etc, rather then the generic "Could not complete file" that it used to. I think this is a good thing, just wanted to note that it does have user-facing implications.

> completeFile should check that the caller still owns the lease of the file that it's completing. This is for the 'testCompleteOtherLeaseHoldersFile' case in HDFS-1139.
