>             Project: Ambari
>          Issue Type: Bug
>          Components: security
>    Affects Versions: 2.3.0, 2.2.0, 2.4.0

> AMBARI-12415 introduces a major security hole to a secure cluster, it adds *dr.who* into *yarn.admin.acl*, which grants yarn admin permission to an anonymous user. It should be reverted. 
> There is an alternative way of fixing this, see more in HADOOP-13707. Http service could be non-secure in a kerberized environment, when hadoop.http.authentication.type=simple, under this situation, the fix of HADOOP-13707 skips admin checks for static user dr.who.
