> Currently Spark SchedulerBackend has no mechanism to be notified of preemption of executors by cluster manager, this will make SchedulerBackend keep scheduling tasks on the to-be-preempted executors and finally be failed. Also this cumulative failure will possibly lead to job failure.
> So Spark SchedulerBackend should be notified and avoid scheduling tasks on preemption nodes to avoid unnecessary failure.
