Description

When browsing using the new FS browser in the namenode, if I try to browse a folder that I don't have permission to view, it throws the error:

Failed to retreive data from /webhdfs/v1/system?op=LISTSTATUS, cause: Forbidden

WebHDFS might be disabled. WebHDFS is required to browse the filesystem.

The reason I'm not allowed to see /system is because I don't have permission, not because WebHDFS is disabled.
