I've seen some traffic where people discuss using multiple reduces, and I'd
like to understand more about this.
If you do multiple reduces, does that mean from a data flow perspective:
map() -> reduce0() -> reduce1() ->...->reduceN-1() -> reduceN() ?
From an implementation point of view, how do you go about setting up multiple
reduces?
Thanks for any advice or pointers to info...
