Add support for query rewrite from the metadata
-----------------------------------------------
Key: HIVE-2847
URL: https://issues.apache.org/jira/browse/HIVE-2847
Project: Hive
Issue Type: New Feature
Reporter: Namit Jain
A simple query like:
select count(1) from T
should be able to get the results from the metadata instead of scanning the
complete input table T.
2. the metadata only queries today does not scale to a very large number of
partitions - that needs to be fixed.
