I'm curious as to how much specific K8s guidance we should be giving in
Spark documentation. There is such a thing as over-documenting; though we
should certainly bias towards writing more documentation. But users can
research Kubernetes-specific concepts using the Kubernetes docs.
For example, when using the volume mounts feature, the user has to provide
a volume type. These volume type strings have very specific semantics and
functionality that is well defined in the Kubernetes docs. So, if the user
provides a `hostPath` volume, can we expect that the user would have already
looked at Kubernetes documentation to know what those kinds of volumes can do?
