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. > 2) So, I should be able to use the hadoop.contrib.index with HDFS. > Though, it would be much better if it is integrated with "Distributed > Lucene" or the "Katta project" as these are designed keeping the > structure and behavior of indexes in mind. Right? 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. Ning
