Subject [jira] Created: (SOLR-1045) Build Solr index using Hadoop MapReduce

Build Solr index using Hadoop MapReduce

                 Key: SOLR-1045
             Project: Solr
          Issue Type: New Feature
            Reporter: Ning Li

The goal is a contrib module that builds Solr index using Hadoop MapReduce.

It is different from the Solr support in Nutch. The Solr support in Nutch sends a document
to a Solr server in a reduce task. Here, the goal is to build/update Solr index within map/reduce
tasks. Also, it achieves better parallelism when the number of map tasks is greater than the
number of reduce tasks, which is usually the case.
