------------------------------------
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.
