Fix Version/s: 2.0.0
> Race condition between on_success_callback and LocalTaskJob's cleanup
> ---------------------------------------------------------------------
>
> Key: AIRFLOW-2865
> URL: https://issues.apache.org/jira/browse/AIRFLOW-2865
> Project: Apache Airflow
> Issue Type: Bug
> Reporter: Marcin Mejran
> Priority: Minor
> Fix For: 2.0.0
>
>
> The TaskInstance's run_raw_task method first records SUCCESS for the task
> instance and then runs the on_success_callback function.
> The LocalTaskJob's heartbeat_callback checks for any TI's with a SUCCESS
> state and terminates their processes.
> As such it's possible for the TI process to be terminated before the
> on_success_callback function finishes running.
