The design of Katta and that of Distributed Lucene are quite different
last time I checked. I pointed out the Katta project because you can
find the code for Distributed Lucene there.

As described in the README file, hadoop.contrib.index uses map/reduce
to build Lucene instances. It does not contain a component that serves
queries. If that's not sufficient for you, you can check out the
designs of Katta and Distributed Index and see which one suits your
use better.
