Description

Deleting the operator helm chart triggers the following error in the jobmanager:

Caused by: io.fabric8.kubernetes.client.KubernetesClientException: Operation: [list]  for kind: [ConfigMap]  with name: [null]  in namespace: [default]  failed.
...
Caused by: java.io.FileNotFoundException: /opt/flink/.kube/config (No such file or directory)

Need to look into why this is happening and should try to avoid it.
