Class SolrReducer

  • public class SolrReducer
    extends <any>
    This class loads the mapper's SolrInputDocuments into one EmbeddedSolrServer per reducer. Each such reducer and Solr server can be seen as a (micro) shard. The Solr servers store their data in HDFS. More specifically, this class consumes a list of <docId, SolrInputDocument> pairs, sorted by docId, and sends them to an embedded Solr server to generate a Solr index shard from the documents.
