Facing issue with local to auth rules.
ambari-qa-cl1@EXAMPLE.COM is getting converted to ambari-qa-cl1 as well as ambari-qa with same ambari configuration ie authentication.kerberos.auth_to_local.rules=DEFAULT.
1st translation :

2nd translation :
28 Jan 2017 11:47:36,425 INFO [ambari-client-thread-3172] AmbariAuthToLocalUserDetailsService:102 - Translated ambari-qa-cl1@EXAMPLE.COM to ambari-qa using auth-to-local rules during Kerberos authentication.
28 Jan 2017 11:47:36,428 WARN [ambari-client-thread-3172] AmbariAuthToLocalUserDetailsService:136 - Failed find user account for user with username of ambari-qa during Kerberos authentication.
Since authentication.kerberos.auth_to_local.rules=DEFAULT , 'ambari-qa-cl1@EXAMPLE.COM' should have been translated to 'ambari-qa-cl1'.
