Jonathan Hurley commented on AMBARI-7985:
-----------------------------------------

[~rlevas] - It looks like your patch increased the test time from 35 minutes to over 47 minutes causing the builds to timeout. How many tests did you add? Are they spinning up a database - that's usually what adds time to the test suite. I've actually never seen a patch increase the test time this much.

> 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
