> 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.
