Namenode crashes in 2.7.2

kumar r-3
Hi,

In Hadoop-2.7.2, i am getting same error reported in here https://issues.apache.org/jira/browse/HDFS-12985

Is there patch available for hadoop-2.7.2 version? How can i restart namenode without null pointer exception?

Thanks,
Kumar

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.
