lukeknxt opened a new issue, #22970:
URL: https://github.com/apache/airflow/issues/22970

   ### Apache Airflow version
   
   2.2.3
   
   ### What happened
   
   When a task instance is in a failed state (or any other non running state), 
and then it's marked as successful through the UI, the `on_success_callback` 
set on the task instance is not run.
   
   ### What you think should happen instead
   
   The `on_success_callback` should run when marking a task instance successful 
from the UI regardless of its state.
   
   
   ### How to reproduce
   
   - Create a DAG
   - Add a task with an `on_success_callback` that throws an exception (so it 
fails)
   - Run the DAG in the UI
   - Wait for the task instance to fail for that DAG run
   - Mark the task instance successful in the UI for that DAG run
   
   ### Operating System
   
   Debian 10 (Buster)
   
   ### Versions of Apache Airflow Providers
   
   `apache-airflow-providers-databricks==2.5.0`
   
   This is the main provider we care about at the moment.
   
   ### Deployment
   
   Other Docker-based deployment
   
   ### Deployment details
   
   _No response_
   
   ### Anything else
   
   From my observations, it seems as though the `on_success_callback` _is_ run 
when a task instance is in a `RUNNING` state, and then is marked successful 
from the UI, but not when the task instance is in any other state. From some 
brief digging this behaviour appears to be related to [the 
`heartbeat_callback`](https://github.com/apache/airflow/blob/e09b4f144d1edefad50a58ebef56bd40df4eb39c/airflow/jobs/local_task_job.py#L236)
 based on [this old bug 
report](https://issues.apache.org/jira/browse/AIRFLOW-6821) but I can't see any 
equivalent logic for when the task _isn't_ running.
   
   For context - we are using this behaviour to track issues occurring in 
Airflow with a 3rd party tool where marking a task instance as successful is 
effectively an "ignore", and our `on_success_callback` lets us register that 
ignore to another tool that tracks alerting.
