Review comment:
I think parts of that change actually pose a similar issue. Basically, the
part that deals with how to stage dependencies for cluster-mode submissions,
since each backend may do something slightly different (like YARN does its own
thing, even if the "copy files to HDFS" part is somewhat similar).
But in this particular case, this big chunk of reflection code is begging to
just be turned into a plugin. You don't need fully hash out that plugin
interface, but at least add the basics of what you're trying to achieve in this
PR to it. We can look at adding more things later as needed.
