>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-server
>    Affects Versions: 2.0.0
>            Reporter: Robert Levas
>            Assignee: Robert Levas
>            Priority: Critical

> 1. Installed cluster on three hosts c6401, c6402, c6403
> 2. using oracle jdk 1.7, put JCE in place on all hosts
> 3. ambari-agent stop on c6403 (which just has DN, ZK and NM)
> 4. Enable kerberos, which means c6403 does not get keytabs
> 5. ambari-agent start on c6403
> 6. go to regen keytabs. Clicked to only do missing. c6403 does not get keytabs.
> 7. go to regen keytabs. just left the default which should do all. No hosts get the keytabs.
> What I found is since the Kerberos client didn't get installed on c6403, the "Set keytab kerberos client" command is "Host Role in invalid state". I went to that host, and did install clients from the UI to get the kerberos client installed. Once that happened, I could then regen keytabs.
> The main issue: Regen only works if all hosts can regen. Once c6403 did not have a client, and Host Role in invalid state, it didn't do keytabs for any other hosts.
