> 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.
