              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?

              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.

              After the analysis, the root cause for this issue should be HDFS-140, So, closing this as duplicate.
