Haohui Mai commented on HDFS-5935:
----------------------------------
Thanks for the patch. I think the error message looks good.
{code}
+ var msg = '<p>Failed to retreive data from ' + url + ': ' + err + '</p>';
+ switch(jqxhr.status) {
...
{code}
The first line gives a default value to {{msg}}, then the code uses
{{switch()}} to handle the special cases. It might be a little bit confusing.
Maybe we can convert it into a series of if-else-ifs?

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 2.3.0
> Reporter: Travis Thompson
> Assignee: Travis Thompson
> Priority: Minor
> Attachments: HDFS-5935-1.patch

>
> 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.
