-----------------------------
Summary: Expose Hive optiq operator tree to be able to support
other sql on hadoop query engines
Key: HIVE-8561
URL: https://issues.apache.org/jira/browse/HIVE-8561
Project: Hive
Issue Type: Task
Components: CBO
Affects Versions: 0.14.0
Reporter: Na Yang
Assignee: Na Yang
Hive-0.14 added cost based optimization and optiq operator tree is created for
select queries. However, the optiq operator tree is not visible from outside
and hard to be used by other Sql on Hadoop query engine such as apache Drill.
To be able to allow drill to access the hive optiq operator tree, we need to
add a public api to return the hive optiq operator tree.
