Jakob Homan commented on HADOOP-5467:
-------------------------------------
bq. In that case, don't you want this tool to reside in a directory named
something like src/tools/org/apache/hadoop/tools/fsimage/.... The idea is that
it can be used to view the fsimage as well as modify it, etc.
How about *src/tools/o/a/h/hdfs/tools/offlineImageProcessor*? (or oip might be
better - it's shorter!). That was it's a generic name enough to allow for
future expansion and not lock the code just to being a pretty printer.

> 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.
