When the number of executors is big, and YarnSchedulerBackend.stopped=False after YarnSchedulerBackend.stop() is running, some executor is stoped, and YarnSchedulerBackend.onDisconnected() will be called, then the problem is exists. So i change the code, when removing executor, add this executorId to executorsPendingToRemove, So the YarnSchedulerBackend.onDisconnected() will not send message to executor
