[jira] [Updated] (HIVE-5151) Going green: Container re-cycling in
Tez
[ https://issues.apache.org/jira/browse/HIVE-5151?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gunther Hagleitner updated HIVE-5151:
-------------------------------------
Description:
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)
