Subject [jira] [Commented] (MAHOUT-944) LuceneIndexToSequenceFiles (lucene2seq) utility
Date Thu, 06 Jun 2013 22:56:21 GMT

    [ https://issues.apache.org/jira/browse/MAHOUT-944?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13677630#comment-13677630

Suneel Marthi commented on MAHOUT-944:
--------------------------------------

Grant, the latest commit to trunk is much better, but we are still missing LuceneSeqFileHelper.java

Also, now that we have upgraded to Lucene 4.3 there are bunch of places still referring to
Version.LUCENE_42 that now show up as deprecated, those would need to be modified too. I can
open a separate JIRA for that and commit a fix after we get past the issue this one.

> Here is a lucene2seq tool I used in a project. It creates sequence files based on the
stored fields of a lucene index.
> The output from this tool can be then fed into seq2sparse and from there you can do text
clustering.
> Comes with Java bean configuration.
> Let me know what you think. Some CLI code can be added later on. I used this for a small-scale
project +- 100.000 docs. Is a MR version useful or is that overkill?
> See https://github.com/frankscholten/mahout/tree/lucene2seq for commits and review comments
from Simon Willnauer (Thanks Simon!)
> or the attached patch.
