Lance Norskog commented on MAHOUT-687:
--------------------------------------
The Sampling iterator never drops the first sample.
A minor nit: Iterator.hasNext() is not supposed to change anything, but this
makes it hard to "keep or drop" the final sample.
So, if you want to have a per-object random, that's great. It would be good to
fix that everywhere as a sweep, but sweeps kill patches. Oh well.

> Problems:
> * The uncommons RepeatableRNG classes are the basis of RandomUtils.
> ** These classes cheerfully ignore setSeed.
> * Some people in the project want to move off Uncommons anyway.
> This patch uses the org.apache.commons.math.random.RandomGenerator classes
> instead of org.apache.uncommons.maths.RepeatableRNG classes.
