Steve Loughran commented on HDFS-5935:
--------------------------------------
# the FS browser should be able to look at hdfs-site.xml and know whether or
not webhdfs is enabled.
# is the browser doing loopback or public IP address GETs? If the latter,
there's a whole other set of causes (iptables, hostname wrong, etc). A wiki
entry is the only way to list these & maintain that list
> 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.
