Jeff Eastman commented on MAHOUT-137:
-------------------------------------

This is a bit more efficient patch for the ClusterMapper:

{noformat}
        Canopy value = new Canopy();
        while (reader.next(key, value)) {
          canopies.add(value);
          value = new Canopy();
        }
{noformat}

> 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
