-------------------------------------------
Summary: Custom RM principal causes zookeeper HA state store to be
inaccessible
Key: AMBARI-20877
URL: https://issues.apache.org/jira/browse/AMBARI-20877
Project: Ambari
Issue Type: Bug
Components: ambari-shell
Affects Versions: 2.5.0
Environment: Ambari 2.5 with HDP 2.6
Reporter: Robert Ketcherside
HDP 2.6 stack introduced settings for ACLs on the Yarn Resource Manager HA
state store. In `yarn-site/yarn.resourcemanager.zk-acl` the ACL user is set to
`rm`.
If this user name does not match the primary component of the Yarn RM Kerberos
principal in `yarn-site/yarn.resourcemanager.principal`, then Yarn is unable to
access the state store and RM will stop immediately after start.
During the Kerberos wizard there needs to be a check to see if these settings
are out of sync. Or, the zk-acl setting needs to somehow reference the
principal and extract the primary root through a variable.
