[GitHub] [airflow] yogyang commented on issue #13853: Clearing of historic Task or DagRuns leads to failed DagRun

   Hi, @kaxil would you help identify this, this bug is kind of preventing me from upgrading the Airflow to 2.0 as we do need the ability to rerun the previous dag-runs in case of some error data.
   
   I compared the codes to 1.10.14(which has no this problem):
   
   in 2.0.0 we have skipped the task_instance runs when the dag is found as dag_timout
   https://github.com/apache/airflow/blob/c743b95a02ba1ec04013635a56ad042ce98823d2/airflow/jobs/scheduler_job.py#L1290-L1299
   
   while in 1.10.14, 
   when the dag is found as dag_timeout, we still run the task_instances.
   https://github.com/apache/airflow/blob/c743b95a02ba1ec04013635a56ad042ce98823d2/airflow/jobs/scheduler_job.py#L1290-L1299
   
   seems it has the different cause compared with https://github.com/apache/airflow/issues/13407
