> I am trying to set up airflow with the kubernetes executor. I have cloned airflow 1.10.6 and am building the docker image and then deploying it with kube. The pods are running, the service airflow also starts. The webserver is working fine. But when I check the logs for the scheduler I get the following error.
>  
> {{ERROR - Error while health checking kube watcher process. Process died for unknown reasons
> INFO - Event: and now my watch begins starting at resource_version: 0
