I don't think you understand what the change is doing. The task will still 
fail, because the executor is dying. 

The only thing that changes is the failure reason, which will now be 
"Executor lost", which is actually more correct (any failure caused by races in 
shutdown are basically because the executor is dying). That allows the driver 
to ignore the failure in certain cases like it already does (e.g. YARN 
preempting executors).

I'm hesitant to support the change. If we don't notify the failure to 
driver, the status of the failed task would not be updated, thus not 
rescheduled, perhaps it's not the behavior we expect to see?

Here's the hacky test code for the interested:

```
sc.parallelize(1 to 100, 100).foreach { _ =>
  var shuttingDown = false
  
  while (!shuttingDown) {
try {
  val hook = new Thread {
override def run() {}
  }
  // scalastyle:off runtimeaddshutdownhook
  Runtime.getRuntime.addShutdownHook(hook)
  // scalastyle:on runtimeaddshutdownhook
  Runtime.getRuntime.removeShutdownHook(hook)
  
  Thread.sleep(10)
} catch {
  case ise: IllegalStateException => shuttingDown = true
}
  }

  throw new Exception("Task failure during shutdown.")
}
```

Ran that in two shells, one in a low priority queue and one in a high 
priority one, restarting the high priority one to force several rounds of 
executors being killed by preemption in the low priority queue.
