wuyi updated SPARK-31509:
-------------------------
Description:
Currently, barrier taskset can only be scheduled when all tasks are launched at
same time. As a result, delay scheduling becomes the biggest obstacle for the
barrier taskset to get scheduled. And the application can be easily fail with
barrier taskset when delay scheduling is on. So, probably, we should recommend
user to disable delay scheduling.
BTW, we could still support delay scheduling with barrier taskset if we could
resolve SPARK-24818
