It is necessary to wait for Ctrl+C because the server shutdowns automatically

> 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.
