KMeans is busted? What do you mean by this? The algorithm simply won't
work or just the reuters example?
Thanks

(Assuming you are on HEAD,) I think KMeans is busted -- this has come up
before. I don't know if it is being maintained. Anyone who's willing to
step up and fix it is also welcome to overhaul it IMHO.

IIRC, Reuters used to run on a cluster but no longer does due to some
obscure Lucene changes. In 0.5 it only works in local mode. I really hope
this can be repaired by 0.6 as Reuters is a key entry point into Mahout
clustering for many users.
