@gatorsmile When the flag is enabled, we don't follow Hive on
non-deterministic join conditions.
The difference are:
* Hive allows non-deterministic expressions in equi join keys and other
join conditions. We only allow the kind of expressions as equi join keys.
* From the inspection on Hive, non-deterministic expressions when used as
join conditions, are not treated in different way than deterministic ones. We
pull non-deterministic equi join keys from Join operators.
