shared memory java dbm for map-side joins

                 Key: HIVE-250
                 URL: https://issues.apache.org/jira/browse/HIVE-250
             Project: Hadoop Hive
          Issue Type: Bug
          Components: Query Processor
            Reporter: Joydeep Sen Sarma
            Assignee: Joydeep Sen Sarma

can use either:
- sdbm: http://freshmeat.net/projects/solingerjavasdbm/
- jdbm: http://sourceforge.net/projects/jdbm/

both need modifications to use file mmaps instead of regular file io. will do some testing
to see if there's a major difference between the two.
