RosterIn commented on issue #8296: Make execute and on_kill as abstractmethod in baseoperator URL: https://github.com/apache/airflow/pull/8296#issuecomment-613605288 The problem is also where you need to kill a process on remote machine. https://issues.apache.org/jira/browse/AIRFLOW-3750 This is also not that simple as some operators are not stand alone but a part of series of operators. Think of `CreateMachineOperator` -> 1 or more `RunOperator` -> `TerminateOperator` (Like EMR for example) What functionally will `on_kill()` have in any of them? shall it be just: ``` def on_kill(): pass ```
