Hi,

I had one Flink job running on K8s with 1 job manager and 112 task managers
with slot number 1. The job can run without any issue.

After I setup HA
<https://nightlies.apache.org/flink/flink-docs-release-1.13/docs/deployment/ha/kubernetes_ha/>on
the job with 2 job managers, I noticed that the task managers numbers in
the UI is 54 instead of 112. And the job would not start running with error
msg.

java.util.concurrent.CompletionException:
org.apache.flink.runtime.jobmanager.scheduler.NoResourceAvailableException:
Could not acquire the minimum required resources.


So I double the task managers to 224, then the UI shows 117 task managers
with 5 empty slots, and the job runs again.

So the question is that when I setup HA, I also need to double the task
manager/resource? I don't think it is mentioned anywhere in the doc, so did
I setup HA wrong? Can someone share some input on this?

Thank you.

Rommel
