Adding "list" to verbs helps, do I need to add anything else ?

Subject: stop job with Savepoint
Hello,
I'm running per job Flink cluster, JM is deployed as Kubernetes Job with
restartPolicy: Never, highavailability is KubernetesHaServicesFactory. Job runs
fine for some time, configmaps are created etc. Now in order to upgrade Flink
job, I'm trying to stop job with savepoint (flink stop $JOB_ID), JM exits with
code 2, from log:

Service account (fsp) role has following rules:
rules:
- apiGroups:
- ""
resources:
- configmaps
verbs:
- update
- get
- create
- watch
- patch
- delete
So service account seems allowed to GET configmaps. Also seems service account
was ok to create configmaps during run (no complains in log).
Thanks,
Alexey
