What happened

我通过DS定时调度，使用Cluster模式启动Seatunnel任务。 然后通过DS页面中“工作流实例”->“操作”->“停止”按钮停止这个Seatunnel任务。

结果是，杀死了SeatunnelClient。 但事实上SeatunnelClient在Cluster模式下，只是讲任务提交到SeatunnelServer，真正执行任务在SeatunnelServer。 所以，杀死SeatunnelClient，只在Local模式下有用。 在Cluster模式下，需要调用Seatunnel提供的rest api -> "/hazelcast/rest/maps/stop-job"。

我本想自己实现在结束Seatunnel任务的同时调用这个接口，但我没有看到dolphinscheduler-task-seatunnel或dolphinscheduler-worker支持这样的扩展。

Research direction
Examine the current stop logic in 'dolphinscheduler task seatunnel' and 'dolphinscheduler worker' modules. Identify how tasks are killed and implement a call to Seatunnel's REST API '/hazelcast/rest/maps/stop job' for cluster mode.
