> Change is due to:
> HIVE-17139: Conditional expressions optimization: skip the expression
> evaluation if the condition is not satisfied for vectorization engine. (Jia
> Ke, reviewed by Ferdinand Xu)
> Embedding a raw vector expression outside of VectorizationContext is quite
> non-standard and evidently buggy.
> [~Ferd] [~Ke Jia] I am inclined to revert this change. Comments? CC:
