nodeAffinity does not schedule pods on the required workers

Hi Team,

I have added node affinity as below in CassandraDatacenter object yaml and deployed, I can that this is being added to cassandradatacenter as expected but is not replicating to cassandra statefulset and pods are not scheduling on the required nodes - can you please assist us if I am doing something wrong?

If you require any further information, please let me know.

    insecure: {}
  size: 3
  storageConfig:
    cassandraDataVolumeClaimSpec:
      storageClassName: standard-ssd
      accessModes:
        - ReadWriteOnce
      resources:
        requests:
