So what's the status on integration of commons-math-2.0 in Mahout? Do we need that stuff? Some of their apis are pretty ugly (look at the number of methods you need to implement to qualify to be a "RealVector"), but piggybacking on some of their functionality would be pretty useful (especially stats/regression/distributions as well as the small matrix decomposition stuff).
