> Whenever adding an Atlas Server on a host, if the user executes the first
> command as a "restart" (stop+start) instead of a "start" command, then the
> stop command will fail because Ambari will not have generated any configs yet
> so Atlas' atlas_stop.py will fail.
> To fix it, during a stop command,
> If the pid dir doesn't exist, this means either
> 1. The user just added Atlas service and issued a restart command
> (stop+start). So stop should be a no-op since there's nothing to stop because
> the pid dir does not exist.
> OR
> 2. The user changed the value of the pid dir config and incorrectly issued a
> restart command.
> In which case the stop command cannot do anything since Ambari doesn't know
> which process to kill.
> The start command will spawn another instance.
> The user should have issued a stop, changed the config, and then started it.
> Ambari generated this error.
