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

             Summary: "Rebalance HDFS" fails via Ambari with Kerberos security ON
                 Key: AMBARI-9963
                 URL: https://issues.apache.org/jira/browse/AMBARI-9963
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 1.7.0
            Reporter: Jayush Luniya
            Assignee: Jayush Luniya
             Fix For: 2.0.0


On a Kerberized cluster attempting to issue a 'rebalance' command via Ambari 1.7 UI results
in the following: 

15/02/26 16:02:40 WARN ipc.Client: Exception encountered while connecting to the server :
javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials
provided (Mechanism level: Failed to find any Kerberos tgt)] 

Issuing a kinit via CLI first and then running the HDFS command manually works.
