File be/src/scheduling/admission-controller.cc:

Line 229: Status AdmissionController::Init(StatestoreSubscriber* subscriber) {
> Ah, so the admission controller should be initialized in a 'executor-only' 
Yeah, we need to at least execute the 'AddPoolUpdates' part of the callback. An executor-only
mode is a good way to put it. I agree avoiding the scheduler initialization would be nice.
I can't remember if there was a reason why the AC was owned by the scheduler but it seems
reasonable to hoist it up to ExecEnv.
