The only integration at this point (as far as I can tell) is that Mahout can read the lucene index created by Solr. I agree that it would be nice to swap out the Carrot2 clustering engine with Mahout's set of algorithms but that has not been done yet. Grant has pointed out that you can use Solr's callback system to fire off another task like a mahout job.
