jack updated AIRFLOW-4927:
--------------------------
Affects Version/s: 1.10.6
1.10.5
> Airflow task stuck in Scheduled mode due to pool not existed
> ------------------------------------------------------------
>
> Key: AIRFLOW-4927
> URL: https://issues.apache.org/jira/browse/AIRFLOW-4927
> Project: Apache Airflow
> Issue Type: Bug
> Components: core
> Affects Versions: 1.10.4, 1.10.5, 1.10.6
> Reporter: jack
> Priority: Major
>
> When operator uses pool like the scheduler schedule the task only when slot
> is available.
> We encounter a case where one of our developers did:
>
>
> {code:java}
> op = CustomOperator(
> task_id='id',
> conn_id='con',
> pool='file_default'){code}
>
>
> However file_default was not defined in pools.
> It took us hours to find that the pool does not exist. No error nor any
> indication was given.
>
> Airflow should raise broken DAG exception if trying to use pool that doesn't
> exist. Much like it does for accessing Variable that doesn't exist.
