> We don't actually need QueryConditionBuilder when cbo is enabled since
> predicate push down is handled by calcite (HIVE-20822). One can argue when
> cbo is disabled we might still need that since calcite will not do the push
> down, but that's a minor code path and removing QueryConditionBuilder won't
> cause any correctness issue. So I'd like to remove it for simplicity.
