Hi Kumar, It seems like the fix for this bug addresses the root cause of the problem, but doesn't seem to help when the NameNode already suffers this problem. I would suggest you to download Hadoop 2.7.2, add a try catch block to catch/swallow the NPE exception. Rebuild it and see if the NameNode can start and check point properly & restart again.
