> 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
> Assignee: Attila Magyar
> Labels: security
>
> 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.
