[Users] Questions about components deployment in detail and spark on OCP.

Hi everyone, I am new to ODH. It seems that all the components in ODH will be deployed with kubeflow operator and kustomize manifests. Could you tell me how to deploy such components in detail on OCP in ODH? Another question is about spark on kubernetes. I have noticed that in ODH, If you want to deploy spark thrift server as hiver server2 , spark cluster needs to be deployed on OCP in ODH beforehand. I think, there is a way to submit spark thrift server on kubernetes/OCP <https://spark.apache.org/docs/3.0.3/running-on-kubernetes.html> directly without having spark cluster deployed on OCP. Is there any reason to do so? Cheers, - Kidong Lee.
