Matthias closed FLINK-21594.

Resolution: Duplicate
Hi Bhagi,
it sounds like this is still the issue that is already discussed in
FLINK-21432. Could you move the discussion back into FLINK-21432? Please add
your findings to the older issue if you have followed [~fly_in_gis] proposal of
aligning the Kubernetes namespace.
I'm closing the issue for now.

> Hi Team,
> I deployed standalone Flink session cluster on kubernetes.. i have created
> the HA with 3 job managers. But Flink Web UI is throwing an error saying
> "\{"errors":["Service temporarily unavailable due to an ongoing leader
> election. Please refresh."]}".
> Please help to fix the issue with UI and HA.
> Logs are showing with the Leader election and updated to the all configmaps..
> below configmaps are created in the same namespace where flink cluster is
> running.
> 111-dispatcher-leader
> 111-resourcemanager-leader
> 111-restserver-leader
> but i have one doubt on configmap created, when i described above configmaps
> showing type as flink-native-kubernetes.. But i created cluster with flink
> standalone kubernetes.
> configmap-type: high-availability
> type: flink-native-kubernetes
>
> 2) Let me know how to confirm the whether flink is running on native
> kubernetes or standalone kubernetes.
