I agree with Mark about this. This method doesn't seem worth adding an API
for by default, especially if it will be tricky to implement. For extracting
small samples, takeSample already lets you specify an exact numbers, and for
downsampling large RDDs, most users probably don't need an exact number (and
wouldn't want to pay an extra pass over the data for it). This and other
advanced sampling methods could make a good external package though.
