> Row group elimination has protection for NULL statistics values in
> RecordReaderImpl.evaluatePredicate() which then calls
> evaluatePredicateRange(). But split elimination directly calls
> evaluatePredicateRange() without NULL protection. This can lead to
> NullPointerException when a column is NULL in entire stripe.
