Lance Norskog commented on MAHOUT-840:
--------------------------------------
A couple of points:
# (int) on a double means Math.floor(double). Would it make more sense to round
up or down?
# Leaf.hashCode() needs a matching equals().
** The equals() should compare with an epsilon.
** clamping to (int) is probably not a very good hash function :)
Please add both a unit test and an example.
