[jira] Created: (HIVE-195) map-side joins are not supported

map-side joins are not supported
--------------------------------

                 Key: HIVE-195
                 URL: https://issues.apache.org/jira/browse/HIVE-195
             Project: Hadoop Hive
          Issue Type: New Feature
          Components: Query Processor
            Reporter: Namit Jain
            Assignee: Namit Jain


map-side joins are not supported.

If all the tables but one are small and can fit in memory, the join should be performed on the map-side. Ideally, it should be all cost-based, but
to start with, the user should be given an option to specify that he needs a map-side join.
