Tao Feng commented on AIRFLOW-1406:
-----------------------------------
have you tried --ignore_first_depends_on_past
([https://github.com/apache/incubator-airflow/blob/master/airflow/bin/cli.py#L1425)]
option ?
> ignore_depends_on_past property ignored by backfill

> Key: AIRFLOW-1406
> URL: https://issues.apache.org/jira/browse/AIRFLOW-1406
> Project: Apache Airflow
> Issue Type: Bug
> Components: backfill
> Affects Versions: Airflow 1.8
> Reporter: Tobias Kaymak
> Assignee: Tao Feng
> Priority: Major
>
> Trying to run the following command does not ignore the first depends_on_past
> dependency of the DAG that has depends_on_past set to true:
> {code}airflow backfill -t search_log_sensor -s 2017-07-10 -e 2017-07-11 -I
> google_pipelines{code}
> neither does this one:
> {code}airflow backfill -t search_log_sensor -s 2017-07-10 -e 2017-07-11
> --ignore_depends_on_past google_pipelines {code}
> both result in:
> {code}
> BackfillJob is deadlocked.Some of the deadlocked tasks were unable to run
> because of "depends_on_past" relationships. Try running the backfill with the
> option "ignore_first_depends_on_past=True" or passing "-I" at the command
> line.
> {code}
> Trying to run with
> {code}
> --ignore_depends_on_past=True
> {code}
> yields:
> {code}
> airflow backfill: error: argument -I/--ignore_first_depends_on_past: ignored
> explicit argument 'True'
> {code}
