Resolution: Duplicate
> 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
> {code}
