Better control memory usage in contrib/index
--------------------------------------------

                 Key: HADOOP-5491
                 URL: https://issues.apache.org/jira/browse/HADOOP-5491
             Project: Hadoop Core
          Issue Type: Bug
            Reporter: Ning Li
            Priority: Minor


The combiner was originally designed to work only on the map side. When used on the reduce
side, it may use too much memory.
