[jira] [Created] (HIVE-12956) run CBO in tests with mapred.mode=strict

             Summary: run CBO in tests with mapred.mode=strict
                 Key: HIVE-12956
                 URL: https://issues.apache.org/jira/browse/HIVE-12956
             Project: Hive
          Issue Type: Test
            Reporter: Sergey Shelukhin
            Assignee: Ashutosh Chauhan


There's a strange condition in CBO check that prevents CBO from running in Hive tests (in tests specifically) when mapred.mode is set to strict. I remember seeing it before, and noticed it again recently.
It is both surprising that we wouldn't test CBO in strict mode, and also problematic for some q files because strict mode is going to be deprecated in HIVE-12727. This needs to be removed.
