> Avoid scheduling tasks on preemption executors
> ----------------------------------------------
>
> Key: SPARK-9468
> URL: https://issues.apache.org/jira/browse/SPARK-9468
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core, YARN
> Reporter: Saisai Shao
> Priority: Minor
>
> 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.
