[GitHub] [incubator-dolphinscheduler] xiashao1980 opened a new issue #2867: [QUESTION] How to make current process stop in Python script?
xiashao1980 opened a new issue #2867:
URL: https://github.com/apache/incubator-dolphinscheduler/issues/2867
In my Python script. I want to stop the current process if some condition was true. So how to stop it and report some error message to the UI list?
**Describe the question**
我想在Python节点中当检查到某些条件满足的情况下，我需要停止当前工作流实例并报错。请问是否支持？ 如果用Python脚本实现？
**Which version of DolphinScheduler:**
-[1.2.0]
Thanks.

Sometimes, I need to stop the current instance and ask the user to fix some problems, then resume this flow from the latest step.
I just want to know if there is some existing way to implement this function. Just like return a false result to the worker process. Or use sys.exit(ExitStatus.failure)?

You can try, when some condition was true, throw exception, and failure strategy set to "end".
the node will set to fail.
