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.
