> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Liang-Chi Hsieh
>
> In Optimizer, Filter operator will go through the rules PushDownPredicate,
> CombineFilters and BooleanSimplification.
> Under this rule order, it is possibly that some predicates that should be
> able to push down, can't be pushed down through operators.
> We should fix it.
