> Key: AIRFLOW-41
> URL: https://issues.apache.org/jira/browse/AIRFLOW-41
> Project: Apache Airflow
> Issue Type: Bug
> Components: scheduler, subdag
> Affects Versions: 1.7.1
> Reporter: Bolke de Bruin
> Priority: Major
>
> SubDagOperators essentially create their own mini-scheduler. Which can
> interfere with the main scheduler.
> SubdagOperators check if there is slot available in a Pool. However this slot
> is not claimed at the same time leaving room for main scheduler to also check
> for the slot. Both can then obtain a slot and thus oversubscribe
> A solution could be a centralized PoolHandler that gives out slots
