Re: LuceneIterator throws an IllegalStateException when a null term frequency vector is encountered

I disagree. You should document that you are discarding documents. It is reasonable to not document every lost document and good to throw an exception when too many failures occur. It is almost inevitable with large data that some inputs are malformed. These can't stop the show, but you have to

Please don't log it. Nobody reads logs. Right is right and wrong is wrong. Either throw an exception or ignore it. You can include a ratio of accepted vectors as an output. On Mon, Apr 18, 2011 at 5:52 PM, Christopher Jordan wrote: > I have incorporated this requested change in a new patch that I

I have incorporated this requested change in a new patch that I attached to ticket https://issues.apache.org/jira/browse/MAHOUT-675. It appears that the previous patch has already been applied. Should I repull the repo, make a new ticket, and create a new patch? Thanks, Chris On Apr 18, 2011,
