That was quick! Unfortunately, I don't have a lot of experience with these
tools, but my current tool chain: solr->mahout lucene.vector->mahout canopy->
mahout kmeans -> mahout clusterdump is reporting that exactly one cluster got
written. However, the csv file created using clusterdump is zero length.

I'm also seeing no variation in results despite changing kmeans distance
measurers and canopy t1 and t2 parameters. Am currently running Dirichlet on
my 8k document data set in an attempt to understand the structure of my data

Any advice?
