downeyh opened a new issue #13298:
URL: https://github.com/apache/airflow/issues/13298
**Apache Airflow version**:
2.0
**Environment**:
Python3.6
**What happened**:
I used mutiprocessing Process in PythonOperator callable function, but it
reports an error.
File "/home/xxx/airflow/dags/Gen/SecData.py", line 88, in gen
w.start()
File "/usr/lib64/python3.6/multiprocessing/process.py", line 103, in start
'daemonic processes are not allowed to have children'
AssertionError: daemonic processes are not allowed to have children
**What you expected to happen**:
In airflow1.10, I could use multiprocessing in task function, it works well,
I'm not sure if is't a bug or there are other ways to use multiporcessing in
PythonOperator task function.
