Description

Upgrade nutch to use Lucene 2.4. This release changes the lucene file format. New indexes created by this lucene version will NOT be readable by older versions. Lucene 2.4 can read and update older index formats although updating an older format will convert it to the new format. There are also some performance and functionality improvments.
