Travis Thompson commented on HDFS-5935:
---------------------------------------
Well something else to consider for security is that you'll never get to this
page if you have security enabled and your browser isn't setup or your ticket
is expired, because again, they're running on the same port. I'll still handle
for them, I'm just not sure they'll ever get hit.
> New Namenode UI FS browser should throw smarter error messages
> --------------------------------------------------------------

> Key: HDFS-5935
> URL: https://issues.apache.org/jira/browse/HDFS-5935
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 2.3.0
> Reporter: Travis Thompson
> Assignee: Travis Thompson
> Priority: Minor
>
> 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:
> {noformat}
> Failed to retreive data from /webhdfs/v1/system?op=LISTSTATUS, cause:
> Forbidden
> WebHDFS might be disabled. WebHDFS is required to browse the filesystem.
> {noformat}
> The reason I'm not allowed to see /system is because I don't have permission,
> not because WebHDFS is disabled.
