Lefty Leverenz commented on HIVE-8125:
--------------------------------------
This says Fixed but doesn't say where. I'm trying to figure out the
*hive.cbo.enable* parameter for documentation purposes.
* Patch 9 _seems_ to add *hive.cbo.enable* with a default of "true" and Optiq
in the description.
* But *hive.cbo.enable* was already added by HIVE-7946 with the original
default of "false" and Optiq in the description (merged to trunk on Sept. 23).
* [~hagleitn] changed "Optiq" to "Calcite" when he committed HIVE-8336 to trunk
and branch-0.14 on Oct. 6.
** Both trunk and branch-0.14 have false/Calcite now.
** The CBO branch has false/Optiq.
So I don't find this jira's true/Optiq combination anywhere.
