---------------------------------------

                 Key: HIVE-824
                 URL: https://issues.apache.org/jira/browse/HIVE-824
             Project: Hadoop Hive
          Issue Type: Improvement
          Components: Query Processor
            Reporter: Namit Jain


CombineHiveInputFormat will enable 1 mapper to read multiple files in the same directory. It should be possible to extend it for multiple directories (partitions of the same table),
when the operator tree for those partitions is the same.
