Thanks for raising this discussion, I think putting the connect folder on the
top level is a good idea to promote Spark Connect, while leaving the connect
jvm client in a separate folder looks weird. I suppose there is no contract to
leave all optional modules under `connector`? e.g.
`resource-managers/kubernetes/{docker,integration-tests}`, `hadoop-cloud`. What
about moving the whole `connect` folder to the top level?
Thanks,
Cheng Pan
