Gunther Hagleitner commented on HIVE-5883:
------------------------------------------
When the plan is found in the tez object registry we need to add it to the
global work map. Otherwise vectorized map operator, context aware readers, etc
will still deserialize the plan one more time.
> Plan is deserialized more often than necessary on Tez (in container reuse
> case)
