Strange, but I do the following to get it working. In eclipse I link my project to the lucene...core jar that came with the mahout I downloaded. I then rebuilt my project and execute it to create the index. Then, I return to mahout and execute the mahout lucene.vector ... and it worked.
Hope this helps -- View this message in context: http://lucene.472066.n3.nabble.com/CorruptIndexException-or-NullPointerException-when-creating-vectors-from-Lucene-tp640134p760426.html Sent from the Mahout User List mailing list archive at Nabble.com.
