Sean Owen commented on MAHOUT-687:
----------------------------------
OK, that is still not what the patch does though.
I think there are two good ideas in the mix here that can be committed without
controversy. First, work around setSeed() behavior by instantiating a new RNG
when called. Second, don't use a shared RNG in the sampling Iterator. I suggest
this is the substance of what to commit in this thread.

> 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.
