Solr Deduplicate - Class Not Found Exception

Hi, I’m running Nutch 2 on a Hadoop 1.2.1 cluster with 2 nodes. I’m running Solr 4 separately on a box and I replaced Solr’s schema with Nutch’s Solr-4 schema. When I run a crawl, I get the following error at the end of the job 14/05/26 14:08:32 INFO solr.SolrDeleteDuplicates: SolrDeleteDuplica

Solr - Cores not initialised
