He Yongqiang updated HIVE-1213:
-------------------------------

    Attachment: Hive-1213.1.patch

Still need one more change to convert the mapjoin to a sorted merge map join. 
Will update the patch after that change.

> sort-merge join does not work for sub-queries

> A query like:
> select count(1) from (select /*+ MAPJOIN(x) */ from x join y ON ... ) subq;
> does not work - since there is no mapping between the join operator and the 
> corresponding source
