Add support for index joins in Hive

    Details

      Description

      Hive supports indexes, which are used for filters currently.

      It would be very useful to add support for index-based joins in Hive.
      If 2 tables A and B are being joined, and an index exists on the join key of A,
      B can be scanned (by the mappers), and for each row in B, a lookup for the corresponding row in A can be performed.
      This can be very useful for some usecases.
