          Thanks Todd for your comments.
          We have tested in our cluster in long run scenarios also.

          But i will check the HDFS-381 defect also.

          This patch looks similar to HDFS-381. I'm hesitant to include it in 0.20-append since it has no serious ramifications and touches NN internals. Have you tested it on a real cluster for any length of time?
