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.
