             Summary: Kubernetes executor scheduler consistently using up CPU
                 Key: AIRFLOW-2969
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-2969
             Project: Apache Airflow
          Issue Type: Bug
            Reporter: Jon Davies


I've deployed Airflow with the Kubernetes executor, and it consistently sits 
there using up CPU cycles when completely idle (no DAGs enabled or running):

{code:java}
kubectl top pods -n production-airflow
...
airflow-scheduler-56cc4d7c97-2lszr   776m         113Mi
...
{code}

When I launch a DAG, this shots up to 2 CPUs used but we're not seeing this 
behavior on our non-Kubernetes Airflow instances.
