------------------------------------
Summary: Requeue Celery tasks in RESERVED state
Key: AIRFLOW-1569
URL: https://issues.apache.org/jira/browse/AIRFLOW-1569
Project: Apache Airflow
Issue Type: Bug
Reporter: Alex Guziel
Assignee: Alex Guziel
Right now, "fair" scheduling in Celery doesn't quite work (some tasks get
RESERVED, which means they will get blocked from execution even if there are
open slots). We should requeue them after 2 heartbeats.
