> When a executor received a TERM signal, it (the second TERM signal) will lock java.lang.Shutdown class and then call Shutdown.exit() method to exit the JVM.
>  Shutdown will call SparkShutdownHook to shutdown the executor.
>  During the executor shutdown phase, RemoteProcessDisconnected event will be send to the RPC inbox, and then WorkerWatcher will try to call System.exit(-1) again.
>  Because java.lang.Shutdown has already locked, a deadlock has occurred.
