Grant Ingersoll updated MAHOUT-137:
-----------------------------------
Attachment: MAHOUT-137.patch
Canopy tests pass. Ran the Synthetic control in local mode and it works, but
haven't validated the output, as we need to write up the OutputDriver that
takes in a sequence file and outputs GSON.
Added the need to pass in the concrete Vector implementation. Also changed
computeCentroid to return Vector (the actual implementation is still Sparse,
but we should reserve the flexibility)
> Convert Clustering Algs to use Vector Writable

> 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
