> Suggested in HDFS-5975.
> Add an option to exposes the read-only version of WebHDFS API for OfflineImageViewer.
You can imagine it looks very similar to jhat.
> That way we can allow the operator to use the existing command-line tool, or even the
web UI to debug the fsimage. It also allows the operator to interactively browsing the file
system, figuring out what goes wrong.
