this looks reasonable to me. As you've done, the important thing is just
to make isSplittable return false.
this shares a bit in common with the sc.wholeTextFile method. It sounds
like you really want something much simpler than what that is doing, but
you might be interested in looking at that
Greetings!
I would like to know if the code below will read one-partition-at-a-time,
and whether I am reinventing the wheel.
If I may explain, upstream code has managed (I hope) to save an RDD such
that each partition file (e.g, part-r-0, part-r-1) contains exactly the
data subset
