> There have been cases in the past where a manual step required after performing a stack upgrade was to regenerate keytabs. This was necessary for a variety of reasons, but it wasn't problematic enough to warrant Ambari doing this as part of an upgrade.
> With the stack upgrade from HDP 2.6 to 3.0, 2 new components are added: Registry DNS and ATR. If the cluster is kerberized, these new components won't start until keytabs have been generated for them.
> The follow will be able to be added to an upgrade pack in order to instruct the upgrade to regenerate missing keytabs for the new components:
> {code}
>     <group xsi:type="cluster" name="REGENERATE_KEYTABS" title="Regenerate Missing Keytabs">
>       <condition xsi:type="security" type="kerberos"/>
>       <direction>UPGRADE</direction>
>       <execute-stage title="Regenerate Missing Keytabs">
>         <task xsi:type="regenerate_keytabs"/>
>       </execute-stage>
>     </group>
> {code}
> A credential store will need to be setup before hand so that the kerberos credentials are available when this step in the upgrade runs.
