Till Rohrmann commented on FLINK-22044:
---------------------------------------
The Flink client tries to connect to localhost/127.0.0.1:8081 to submit the
job. I think you need to tell Flink where the JobManager pod is running. You
can do this via port-forwarding onto the machine where you want to submit the
job. Flink's [K8s
documentation|https://ci.apache.org/projects/flink/flink-docs-stable/deployment/resource-providers/standalone/kubernetes.html#starting-a-kubernetes-cluster-session-mode]
contains an example how to do it.
