Great link. Thanks a lot.

Cooccurrence analysis is commonly used in recommendations. These produce
large intermediates.
Come on over to the Mahout project if you would like to talk to a bunch of
people who work on these problems.

I got 2 questions:
1. I am wondering how hadoop MR performs when it runs compute intensive
applications, e.g. Monte carlo method compute PI. There's a example in 0.21,
QuasiMonteCarlo, but that example doesn't use random number and it generates
psudo input upfront. If we use distributed random num
