Review request for hive and Aihua Xu.
Bugs: HIVE-11401
https://issues.apache.org/jira/browse/HIVE-11401
Repository: hive-git
Description
-------
The following patch reviews the predicate created by Hive, and removes any
column that does not belong to the Parquet schema, such as partitioned columns.
This way Parquet can filter the columns correctly.
