Hi All,
I am deploying Flink cluster on Kubernetes in HA mode. But i noticed,
whenever i deploy Flink cluster for first time on K8s cluster, it is not
able to populate the cluster configmap, and due to which JM fails with the
following exception:
2023-07-06 16:46:11,428 ERROR
org.apache.flink.runtime.entrypoint.ClusterEntrypoint [] -
Fatal error occurred in the cluster entrypoint.
java.util.concurrent.CompletionException:

Once we reinstall/helm upgrade then this exception goes away. How can this
be resolved, any additional configuration required to resolve this?
I am using the following configuration for HA:
high-availability.storageDir: file:///opt/flink/pm/ha
kubernetes.cluster-id: {{ include "fullname" . }}-cluster-{{ now |
date "20060102150405" }}
high-availability.jobmanager.port: 6123
high-availability.type: kubernetes
high-availability:
org.apache.flink.kubernetes.highavailability.KubernetesHaServicesFactory
kubernetes.namespace: {{ .Release.Namespace }}
Thanks
Regards
