> org.apache.ambari.server.actionmanager.ActionScheduler#filterParallelPerHostStages
> should not filter out stages that contain server-side actions (to be
> executed on the Ambari server host). This is because tasks in these stages
> are typically required to complete before other stages on other hosts are
> executed.
> For example while enabling Kerberos for an added service, principals and
> keytab files need to be created before the stage to distribute the key tab
> files. The principal and keytab file creation happens on the Ambari server
> (as server-side actions) and the distribution tasks happen on the relevant
> hosts. If the server-side stages are filtered out (in the event multiple
> stages are pending for the Ambari server host), then one or more might be
> skipped and the distribution task is queued. In this scenario, the
> distribution stage will fail since the required keytab files will not have
> been created.
