Grant Ingersoll commented on MAHOUT-137:
----------------------------------------
The KMeans examples seem a bit trickier, b/c they seem to be abusing the fact
that the output of Canopy looks very much like a Cluster as well when viewed as
Text. Unfortunately, the KMeansMapper is looking for a Cluster object, but is
getting a Canopy.
Any thoughts on how to remedy?

> All M/R jobs should use Vector writable instead of encoding and decoding
> strings. We can have a separate utility that converts serialized GSON,
> Strings, whatever into the appropriate vectors. See MAHOUT-136 and
