Create an offline fsimage image viewer

                 Key: HADOOP-5467
                 URL: https://issues.apache.org/jira/browse/HADOOP-5467
             Project: Hadoop Core
          Issue Type: New Feature
          Components: util
            Reporter: Jakob Homan
            Assignee: Jakob Homan

It would be useful to have a tool to examine/dump the contents of the fsimage file to human-readable
form.  This would allow analysis of the namespace (file usage, block sizes, etc) without impacting
the operation of the namenode.  XML would be reasonable output format, as it can be easily
viewed, compressed and manipulated via either XSLT or XQuery.  

I've started work on this and will have an initial version soon.
