> Today Start, or Start All buttons for an individual service are greyed out if all masters are started. The issue is if you have a lot of workers that are not started, you still want to start/start all to get them started. We should change the behavior so it's more like this:
> Any component Stopped -> "Start/Start All" is available
> All components Started -> "Start/Start All" is not available
> All components (that are not in maintenance mode or on hosts in maintenance mode) are Started -> "Start/Start All" is not available
> That way if any component is stopped we can start it with a Start/Start All. The behavior should be that Ambari looks at all components for the service and if any are in the stopped state, it will start those components. Maintenance mode should be respected and if a component or host is in maintenance mode, they will be ignored from this.
