[Spark branch]
                 Key: HIVE-9294
                 URL: https://issues.apache.org/jira/browse/HIVE-9294
             Project: Hive
          Issue Type: Task

            Reporter: Szehon Ho
            Assignee: Jimmy Xiang

During a mapjoin, we might be able to improve replication factor of small table files, given
the number of partitions in the big table.  This JIRA is to track investigation of that.

Note, this JIRA might be pending potential changes to mapjoin algorithm.
