Shixiong Zhu 2aecda284e [SPARK-12281][CORE] Fix a race condition when reporting ExecutorState in the shutdown hook 
1. Make sure workers and masters exit so that no worker or master will still be running when triggering the shutdown hook.
2. Set ExecutorState to FAILED if it's still RUNNING when executing the shutdown hook.

This should fix the potential exceptions when exiting a local cluster
```
