Review request for hive and Jason Dere.


Repository: hive-git


Description
-------

Semijoin Hint : Should able to handle more than 1 hint per alias.
- If a user provides a hint, only that semijoin optimization is performed.
- If there are more than 1 hints for an alias, it is upto user to make sure the (alias + colName)
combo is unique.
- Works with join aliases.
- Refactored the logic to generate semijoin to keep the inner loops count down.
