I'm not doing too well here.
I followed the instructions supplied here, with a current .3 dev tree
and the correct hadoop, and got the following. I definitely my
0.3-SNAPSHOT Driver from my local build. This is assuming, of course,
that I can just feed the vectors from
org.apache.mahout.utils.vectors.lucene.Driver straight into the sample
KMeans job. Maybe I need to feed them directly to the KMeans class,
instead?
