Konstantin Shvachko updated HDFS-2285:

       Resolution: Fixed
    Fix Version/s: 0.24.0
     Hadoop Flags: Reviewed
           Status: Resolved  (was: Patch Available)

I just committed this to trunk. Thank you Uma.

The patch does not apply to 0.23 branch any more. I recommend it for back porting.
