Tao Feng commented on AIRFLOW-2768:
-----------------------------------
Hey [~7yl4r] , have you tried `airflow backfill --rerun_failed_tasks` ? By
doing so, airflow will auto rerun only the failed task during backfill.
> `airflow clear --upstream --only_failed` doesn't clear tasks upstream

> Key: AIRFLOW-2768
> URL: https://issues.apache.org/jira/browse/AIRFLOW-2768
> Project: Apache Airflow
> Issue Type: Bug
> Components: cli
> Affects Versions: 1.9.0
> Environment: airflow v1.9.0
> Reporter: Tylar Murray
> Priority: Major
> Labels: cli
>
> Should `airflow clear --upstream --only_failed mydagname` clear non-failed
> tasks upstream of a failed task?
> I believe so, yes. If not, then `airflow clear --upstream --only_failed` and
> `airflow clear --only_failed` are equivalent.
> Upstream tasks are not being cleared. The same is true for `–downstream`.
>
> My use-case is: I want to clear all tasks all DagRuns that contain a failed
> task. In other words: `airflow clear mydagname`, but skip DagRuns that have
> completed sucessfully.
