> In our case, we are implementing restartable resource manager mechanism which will let master executor survive when resource manager service is temporarily down. So when resource manager service is not available, scheduler should stop scheduling new tasks. I added a hook inside CoarseGrainedSchedulerBackend class, in order to avoid new task scheduling  when it's necessary.
