> We meet a case that user call sc.stop() after run all custom code, but stuck in some place.
> Cause below situation
> # User call sc.stop()
> # sc.stop() stuck in some process, but SchedulerBackend.stop was called
> # Since tarn ApplicationMaster didn't finish， still call YarnAllocator.allocateResources()
> # Since driver endpoint stop new allocated executor failed to register
> # untll trigger Max number of executor failures
> Caused by
> Before call CoarseGrainedSchedulerBackend.stop() will call YarnSchedulerBackend.requestTotalExecutor() to clean request info

>
> From the log we make sure that CoarseGrainedSchedulerBackend.stop() was called
>
>
> When YarnAllocator handle then empty resource request, since resourceTotalExecutorsWithPreferedLocalities is empty, miss clean targetNumExecutorsPerResourceProfileId.
