It's expected. There have been constant api changes between lucene versions and the code may need some tweaking. All the errors u r seeing are in mahout-integration which Culd be from lucene2seq utility which is tightly bound to lucene. Go with the latest lucene version and please open a Jira and feel free to submit a patch.
