> Suggested in HDFS-5975.
> Add an option to OfflineImageViewer to launch HTTP server that takes fsimage and exposes
the read-only version of WebHDFS API for OfflineImageViewer. The server only supports {{LISTSTATUS}}
operation and other operations such as {{GETFILESTATUS}} will be added by other JIRAs.
> 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.
