Looks like this won't make it into this build. Pretty widespread impact
on code and tests and I don't know which properties were implemented in
the old version. I will create a JIRA and post my interim results.

That's a reversion that evidently got in when the new
ClusterClassificationDriver was introduced. It should be a pretty easy
fix and I will see if I can make the change before Paritosh cuts the
release bits tonight.

It appears that in kmeans the clusteredPoints are now written as
WeightedVectorWritable where in mahout 0.6 they were
WeightedPropertyVectorWritable? This means that the distance from the
centroid is no longer stored here? Why? I hope I'm wrong because that
is not a welcome change. How is one to order clustered docs by
distance from cluster centroid?
I'm sure I could calculate the distance but that would mean looking
up the centroid for the cluster id given in the above
WeightedVectorWritable, which means iterating through all the
clusters for each clustered doc. In my case the number of clusters
could be fairly large.
Am I missing something?
