Yup! The top-level pom.xml file in mahout gives Lucene 3.3 as the requested version. You need to either: 1) back-rev your Solr to 3.3, OR 2) upgrade your Mahout to use Lucene 3.4 instead of 3.3. You may have to make some simple changes in the Mahout code which uses Lucene to match any API changes, but there should not be any real differences.
