> In a high concurrency scenario, we can see from the spark-ui that there are a lot of jobs running all the time, but only a few sql are actually running
> As you can see from the attachment, there are many active jobs on the spark-ui. In fact, I stopped submitting jobs at 30 minutes, and after 14 minutes, there are still many jobs on the spark-ui whose status cannot be updated, and which have actually completed
> To solve the problem, I tried to set spark.scheduler.listenerbus.eventqueue.capacity = 600000, but it didn't work
