------------------------------------

             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.
