Flink(1.12.2/scala 2.11) HA with Zk in kubernetes standalone mode deployment is not working

Hi Team,

I deployed kubernetes standalone deployment flink cluster with ZK HA, but
facing some issues, i have attached taskmanager and job manger logs.

Can you please see the logs and help me solve this issue.

UI is throwing this error:

{"errors":["Service temporarily unavailable due to an ongoing leader
election. Please refresh."]}

jobmanager.log

Hi Bhagi,
Thanks for reaching out to the Flink community. The error the UI is showing
is normal during an ongoing leader election. Additionally, the connection
refused warnings seem to be normal according to other mailing list
threads. Are you referring to the UI error as the issue you are facing?

What puzzles me a bit are the timestamps of your provided logs. They do not
seem to be fully aligned. Are there more logs that might indicate other
issues?

Matthias

PS: I'm gonna add the user mailing list as this issue should usually be
posted there.
