> Tez reuses containers to schedule tasks from same and different vertices in the same JVM. It also offers an API to reuse objects across vertices, dags and sessions.
> For hive we should reuse the operator plan as well as any hash tables (map join).
> NO PRECOMMIT TESTS (this is wip for the tez branch)
