    • Release Note:
      New Offline Image Viewer (oiv) tool reads an fsimage file and writes the data in a variety of user-friendly formats, including XML.

      Description

      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.
