goals (copied over from SPARK-5741 comments by @marmbrus ):
It was originally just parquet that would support more than one file, but
now all HadoopFSRelations should. (which covers all but CSV, and we should
upgrade that library too) I would be in favor of generalizing this support for
at least these sources given the following constraints:
* We must keep source/binary compatibility.
* We should give good errors when the source does not support this feature.
* For consistency, I'd prefer if we can just add a load(path: String*) (but
I'm not sure if this is possible given the above).
* paths(path: *) is okay, but I think I'd prefer if it was not the terminal
operator.
I believe these goals are met here.
