> {{WebImageViewer}} will get the following error if there is an empty directory is in
{{/user/root/}}.
> {code}
> [root@trunk ~]# hdfs dfs -ls -R webhdfs://localhost:5978/user/root/
> ls: Unexpected HTTP response: code=404 != 200, op=LISTSTATUS, message=Not Found
> {code}
> The reason of the error is that {{WebImageViewer}} returns 404 (not found) if {{LISTSTATUS}}
to an empty directory. It should return 200 (ok) and empty FileStatuses.
