[jira] [Created] (AMBARI-18632) Security flaw with adding dr.who into yarn.admin.acl while enabling kerberos

Weiwei Yang created AMBARI-18632:
------------------------------------

             Summary: Security flaw with adding dr.who into yarn.admin.acl  while enabling kerberos
                 Key: AMBARI-18632
                 URL: https://issues.apache.org/jira/browse/AMBARI-18632
             Project: Ambari
          Issue Type: Bug
          Components: security
    Affects Versions: 2.3.0, 2.2.0, 2.4.0
            Reporter: Weiwei Yang


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.
