      Description

      1) Test Kerberos Client dialog shows an "n/a" entry and when you click on it, throws a JS error. See attached. The n/a appears to represent the command run on the Ambari Server itself.
      2) All Ambari server ops throw JS error. On other places in the wizard, it shows "Ambari Server Host" but that throws JS.
      3) same for regen keytabs. basically all over the place

            }
          }
        ]
      }
      

      Solution
      On the backend, convert null host name values to the FQDN of the Ambari server before returning response.
