----------------------------------

             Summary: Add an option to the NameNode that prints the software 
and on-disk image versions
                 Key: HDFS-6572
                 URL: https://issues.apache.org/jira/browse/HDFS-6572
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
            Reporter: Charles Lamb
            Assignee: Charles Lamb
            Priority: Minor


The HDFS namenode should have a startup option that prints the metadata 
versions of both the software and the on-disk version. This will be useful for 
debugging certain situations.
