Subject [jira] [Commented] (HDFS-5935) New Namenode UI FS browser should throw smarter error messages
Date Wed, 12 Feb 2014 23:17:22 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5935?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13899744#comment-13899744

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.

>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: namenode
>    Affects Versions: 2.3.0

> 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.
