>             Project: Hadoop Common
>          Issue Type: Bug
>    Affects Versions: 2.8.0, 2.7.4
>            Reporter: Jeffrey E  Rodriguez
>            Assignee: Yuanbo Liu

> User Hadoop on secure mode.
> login as kdc user, kinit.
> start firefox and enable Kerberos
> access http://localhost:50070/logs/
> Get 403 authorization errors.
> only hdfs user could access logs.
> Would expect as a user to be able to web interface logs link.
> Same results if using curl:
> curl -v  --negotiate -u tester:  http://localhost:50070/logs/
>  HTTP/1.1 403 User tester is unauthorized to access this page.
> so:
> 1. either don't show links if hdfs user  is able to access.
> 2. provide mechanism to add users to web application realm.
> 3. note that we are pass authentication so the issue is authorization to /logs/
> suspect that /logs/ path is secure in webdescriptor so suspect users by default don't have access to secure paths.
