Can you just try to add https://github.com/opendatahub-io/odh-manifests/blob/master/jupyterhub/jupyterhub/base/jupyterhub-spark-operator-configmap.yaml#L6-L19
to
https://github.com/erikerlandson/ray-hax/blob/master/deploy/ray-cluster-template-cm.yaml
and reference it in
https://github.com/erikerlandson/ray-hax/blob/master/deploy/ray-singleuser-profile-cm.yaml#L18
??
