Subject [jira] [Commented] (HIVE-8125) CBO Trunk Merge: On Failure Fall Back to Non CBO
Date Tue, 21 Oct 2014 15:01:33 GMT

Laljo John Pullokkaran commented on HIVE-8125:
----------------------------------------------

Hi Lefty,
     the fix was originally done in CBO branch which then got ported to Trunk.
CBO branch is not relevant any more as all the CBO development now happens on trunk.

hive.cbo.enable is set to false by default on trunk and branch 14.
We may change this once all of the unit test issues are cleared.

Optiq got renamed to Calcite this month (due to copyright issues); hence old CBO branch uses
Optiq and trunk uses "Calcite".
