cstenkamp opened a new issue #19743:
URL: https://github.com/apache/airflow/issues/19743
### Apache Airflow version
2.1.4
### Operating System
Ubuntu 20.04.3 (airflow in docker-compose)
### Versions of Apache Airflow Providers
_No response_
### Deployment
Docker-Compose
### Deployment details
Docker-Compose stack based on Docker-Image `apache/airflow:2.1.4`
### What happened
When running a DAG using the DebugExecutor (see below), `catchup=False` is
ignored and airflow starts backfilling the task.
### What you expected to happen
With `catchup=False`, Airflow shouldn't schedule all previous tasks but only
the newest one, regardless of the executor
### How to reproduce
```
from datetime import datetime
from airflow.models.dag import DAG
from airflow.operators.dummy import DummyOperator
default_args = {
"start_date": datetime(2021, 11, 10),
"catchup": False,
}
dag_args = dict(
dag_id="accuracy_checker",
schedule_interval=None,
default_args=default_args,
catchup=False,
max_active_runs=1,
)
with DAG(**dag_args) as dag:
start_pipeline = DummyOperator(
task_id="start_pipeline",
dag=dag,
)
finish_pipeline = DummyOperator(
task_id="finish_pipeline",
dag=dag,
)
start_pipeline >> finish_pipeline
if __name__ == "__main__":
from airflow.utils.state import State
dag.clear(dag_run_state=State.NONE)
dag.run()
```
