I am following the Flink official tutorial to start a session in native Kubernetes.
First I created a clean new cluster.
However, after running
./bin/kubernetes-session.sh -Dkubernetes.cluster-id=my-first-flink-cluster
I got error in the pod my-first-flink-cluster-xxx log that just got created:
2021-08-14 18:33:02,519 WARN io.fabric8.kubernetes.client.dsl.internal.WatchConnectionManager [] - Exec Failure: HTTP 403, Status: 403 - pods is forbidden: User "system:serviceaccount:default:default" cannot watch resource "pods" in API group "" in the namespace "default"
