Queries should be optimized with pre-ordered column
---------------------------------------------------
Key: HIVE-735
URL: https://issues.apache.org/jira/browse/HIVE-735
Project: Hadoop Hive
Issue Type: Improvement
Components: Query Processor
Reporter: He Yongqiang
If a table has one or some pre-ordered columns and a query has
filters(range/point) on these columns. Hive should take advantage of the order
information, and only read the needed blocks instead of touching the whole
file. And this will also be useful for sorted summary table index.
