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

             Summary: Zeppelin restart with Ambari fails - according to Ambari
                 Key: AMBARI-16772
                 URL: https://issues.apache.org/jira/browse/AMBARI-16772
             Project: Ambari
          Issue Type: Bug
    Affects Versions: ambari-2.4.0
         Environment: centos
            Reporter: Renjith Kamath
             Fix For: ambari-2.4.0


Configure Zeppelin to authenticate users.
Log in to Zeppelin as a user (let's say user1)
Re-start Zeppelin with Ambai, note Ambari reports Zeppelin fails to restart. However Zeppelin is restarted fine.
Note 401 in the log of the error below. I suspect it is because with authentication enabled Ambari isn't able to contact zeppelin.
