yuqian90 opened a new issue #12485:
URL: https://github.com/apache/airflow/issues/12485


   **Description**
   
   For a DAG that looks like this:
   
   ```
   A >> B
   ```
   
   If A fails, B goes into "upstream_failed" state. If a user then marks A "success", B will remain in "upstream_failed" state. It will not automatically start running. This scenario often happens if the failure of A is dealt with outside of Airflow and the user does not want Airflow to run A again. But he usually expect Airflow to run B after A is marked "success".
   
   **Use case / motivation**
   
   After A is marked "success", its downstream tasks B should be cleared automatically and get ready to be scheduled. To avoid changing this behaviour completely, this can be made optional. I.e. there should be a toggle button next to "Success" that lets the user decide if he wants Airflow to automatically clear downstream tasks that are in "upstream_failed" state.
