[GitBox <gi...@apache.org>]

yyhecust opened a new issue #20942:
URL: https://github.com/apache/airflow/issues/20942


   ### Description
   
   being able to  clear the task on the other DAG and its downstream tasks recursively without ExternalTaskMarker and don't modify dag files.
   
   ### Use case/motivation
   
   In my application, we need to clear the task on the other DAG and its downstream tasks recursively, but when we design the Dag template, we didn't use ExternalTaskMarker and we didn't want to modify the Dag files that were running in production. So, we can't use ExternalTaskMarker to help us clear the task and its downstream tasks over Dag and we want to do this without modifying the dag files.
