> Key: SPARK-32518
> URL: https://issues.apache.org/jira/browse/SPARK-32518
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.0.0
> Reporter: wuyi
> Assignee: wuyi
> Priority: Major
> Fix For: 3.0.1, 3.1.0
>
>
> Currently, CoarseGrainedSchedulerBackend.maxNumConcurrentTasks only considers
> the CPU for the max concurrent tasks. This can cause the application to hang
> when a barrier stage requires extra custom resources but the cluster doesn't
> have enough corresponding resources. Because, without the checking for other
> custom resources in maxNumConcurrentTasks, the barrier stage can be submitted
> to the TaskSchedulerImpl. But the TaskSchedulerImpl can not launch tasks for
> the barrier stage due to the insufficient task slots calculated by
> calculateAvailableSlots(which does check all kinds of resources).
