Build Solr index using Hadoop MapReduce
---------------------------------------

                 Key: SOLR-1045
                 URL: https://issues.apache.org/jira/browse/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.
