--------------------------------------

             Summary: Yarn/MR2 should handle a customized Zookeeper service principal name
                 Key: AMBARI-22824
                 URL: https://issues.apache.org/jira/browse/AMBARI-22824
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-server
    Affects Versions: 2.0.0
            Reporter: Sandor Molnar
            Assignee: Sandor Molnar
             Fix For: 3.0.0


Yarn and MapReduce2 should handle a customized Zookeeper service principal name.

Currently this is not supported due to hardcoded and implicit values expecting the Zookeeper
service principal name to be {{zookeeper/_HOST}} as opposed to something like {{zookeeper-mycluster/_HOST}}.

The following changes need to be made:
 * common-services/YARN/2.1.0.2.0/package/scripts/params_linux.py must be changed to not hardcode
the Zookeeper principal name in
{code:java}
m_security_opts = format('-Dzookeeper.sasl.client=true -Dzookeeper.sasl.client.username=zookeeper
-Djava.security.auth.login.config={yarn_jaas_file} -Dzookeeper.sasl.clientconfig=Client')
{code}

 * {{-Dzookeeper.sasl.client.username=<ZOOKEEPER_PRINCPAL_NAME>}} should be added to {{YARN_OPTS}}
