             Summary: Task_instance and Dag_run recycle
                 Key: AIRFLOW-1778
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1778
             Project: Apache Airflow
          Issue Type: Wish
          Components: DagRun
    Affects Versions: 1.8.1
            Reporter: Alessio Palma


Hello, I'm not sure this is a real issue but something strange happened on our airflow installation.

We started a dag which did not complete due to some issues on Hadoop, so we delete all the dag_run affected and left untouched the task_instances  waited for it to complete but... 

1. Every dag restarted with the correct execution date
2. No processor executed for real
3. airflow used the old task_instance record.

So the question is... it was so bad just to delete the dag_run without deleting the task_instances?  Also... If it is bad to delete the dag_run, why it is possible to execute this action from the admin menu? 

Should the delete dag_run option to be removed?
