[jira] Updated: (NUTCH-684) Dedup support for Solr

["Doğacan Güney (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/NUTCH-684?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Doğacan Güney updated NUTCH-684:
--------------------------------

    Attachment: solrdedup_v2.patch

New version:

* Added field names to SolrConstants. Although only SolrDeleteDuplicates uses these.

* Also, I didn't implement a conf option for unique key. It is a very good idea but it also requires changes to SolrIndexer and other classes and I didn't want to do it this late in the release cycle.

* #reduce now uses a UpdateRequest so that deletes are queued and sent to server in batches.

* Added javadoc

* Updated bin/nutch with new command solrdedup

> After NUTCH-442, nutch now can index to both solr and lucene. However, duplicate deletion feature (based on digests) is only available in lucene. It should also be available for solr.
