Subject [jira] [Created] (HIVE-5151) Going green: Container re-cycling in Tez
Date Mon, 26 Aug 2013 20:28:51 GMT
Gunther Hagleitner created HIVE-5151:

             Summary: Going green: Container re-cycling in Tez
                 Key: HIVE-5151
             Project: Hive
          Issue Type: Bug
            Reporter: Gunther Hagleitner
            Assignee: Gunther Hagleitner
             Fix For: tez-branch

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).
