> 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.
