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

             Summary: Wrong user us used to execute the Spark/Livy Server service check
                 Key: AMBARI-22998
                 URL: https://issues.apache.org/jira/browse/AMBARI-22998
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.6.0
            Reporter: Robert Levas
            Assignee: Robert Levas
             Fix For: 2.6.2, 2.7.0


{code:title=common-services/SPARK/1.2.1/package/scripts/service_check.py:36}
 livy_kinit_cmd = format("{kinit_path_local} -kt {smoke_user_keytab} {smokeuser_principal}; ")
 Execute(livy_kinit_cmd, user=params.livy_user)
{code}
Notice the Kerberos identity is for the smoke user, but the exec is for the livy user. This will replace the livy user's interactive Kerberos ticket cache.

This should be 
{code}
smoke_user_kinit_cmd = format("{kinit_path_local} -kt {smoke_user_keytab}
 {smokeuser_principal}; ")
Execute(smoke_user_kinit_cmd, user=params.smoke_user)
{code}
Where {{smoke_user}} is
{code}
smoke_user =  config['configurations']['cluster-env']['smokeuser']
{code}
