> 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.
