Subject [jira] [Created] (AMBARI-14338) Kerberos: all ambari server host ops are broken
Date Fri, 11 Dec 2015 00:17:11 GMT
Robert Levas created AMBARI-14338:
-------------------------------------

             Summary: Kerberos: all ambari server host ops are broken
                 Key: AMBARI-14338
                 URL: https://issues.apache.org/jira/browse/AMBARI-14338
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.2.0
            Reporter: Robert Levas
            Assignee: Robert Levas
            Priority: Blocker
             Fix For: 2.2.0


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.
