Travis Thompson commented on HDFS-5935:
---------------------------------------
It's actually returning a 403, not a 404. I'll have to test with webhdfs off
to see what it throws, but I suspect it's not a 403. Here's the curl output of
that url:

I've found where this going on in the source code and I can take a look at it
in the next few days. It doesn't look like it'll be too hard to add smarter
error handling.
> 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
> 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.
