You can use the ClusterDumper class (I just posted an example at
http://lucene.grantingersoll.com/2010/02/16/trijug-intro-to-mahout-slides-and-demo-examples/)
or you can use the SequenceFile Dumper.
If you generated from a Lucene index, you can also use a class in utilities
(ClusterLabels?) to print out labels based on LLR calculations.
