> Ambari currently handles _client-/agent-side_ commands; however there is no
> ability to handle _server-side_ commands. Server-side commands should be
> specified as a task in a stage and managed along with the stage.
> *Use Case:* Generate principals and keytabs on the Ambari server before
> sending the keytabs to their relevant hosts.
> *Implementation:* To add the concept of a server-side task:
> * update {{org.apache.ambari.server.serveraction.ServerAction}} to be an
> _abstract class_
> ** _server-side_ tasks must implement this class
> * reuse existing _host_role_command_ and _execution_command_ data
> ** _server-side_ tasks are to have a role of {{AMBARI_SERVER_ACTION}}
> ** _server-side_ execution command data should be encapsulated as JSON and
> specify the ServerAction implementation class and any needed payload data
> * {{org.apache.ambari.server.actionmanager.ActionScheduler}} and
> {{org.apache.ambari.server.serveraction.ServerActionManagerImpl}} need to be
> updated to handle the execution of server-side tasks
> ** each _server-side_ task should be executed in its own thread.
> *** _server_side_ tasks should be executed in (staged) order, serially - not
> in parallel
> *** _server_side_ tasks should ensure not to mess up _stage_ ordering
