      Description

      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.
