> 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.
