Spark Kill Application

To kill a Spark application, you can follow these steps:

1. Identify the application ID of the Spark application you want to kill. You can find this ID in the Spark UI or by using the `yarn application -list` command.
2. Once you have the application ID, use the `yarn application -kill <application ID>` command to kill the application. Alternatively, you can also use the `yarn application -kill-all` command to kill all running applications.

Note that killing a Spark application will terminate all running Spark tasks associated with that application. It is recommended to gracefully stop the application using the Spark API or CLI before attempting to kill it.

spark中application和driver的关系是什么

Application和Driver在Spark中是指同一个概念，也就是执行Spark作业的进程。在调度集群资源之前，Application需要有一个Driver进程来协调任务的执行。如果想要在Spark中执行一个作业，必须先启动一个Driver进程，然后通过Driver进程来调度执行各个task的Executor进程。
