Yang Wang commented on FLINK-21432: ----------------------------------- I think you are running multiple JobManagers or maybe something is wrong with your Kuberenetes service "flink-jobmanager". Could you please have a try on the pod IP address? You could find the full yaml files here[1]. The most important changes are about the '--host' argument and '_POD_IP_ADDRESS' env setting.
