eejbyfeldt opened a new issue #14260: URL: https://github.com/apache/airflow/issues/14260
**Apache Airflow version**: 2.0.1 **What happened**: When clearing task across dags using `ExternalTaskMarker` the dag state of the external `DagRun` is not set to active. So cleared tasks in the external dag will not automatically start if the `DagRun` is a Failed or Succeeded state. **What you expected to happen**: The external `DagRun` run should also be set to Running state. **How to reproduce it**: Clear tasks in an external dag using an ExternalTaskMarker. **Anything else we need to know**: Looking at the code is has: https://github.com/apache/airflow/blob/b23fc137812f5eabf7834e07e032915e2a504c17/airflow/models/dag.py#L1323-L1335 It seems like it intentionally calls the dag member method `set_dag_run_state` instead of letting the helper function `clear_task_insntances` set the `DagRun` state. But the member method will only change the state of `DagRun`s of dag where the original task is, while I believe `clear_task_instances` would correctly change the state of all involved `DagRun`s. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
