Yes, it probably would. My understanding of hadoop (which is very
highlevel) is that just dump everything in without too much concern
about the structure / "schema". But I could be wrong on that.

It looks like there is a set that you can use for free. When you go
over one of several metrics (CPU hours/day, storage, bandwidth in,
bandwidth out, etc.), then you have to start paying. But even with
that, the costs look *quite* reasonable and should be easily covered
by the combined Open MPI organizations (I'm talking hundreds of
dollars here, not tens of thousands).
