> With HIVE-17209, it is possible to get empty list when invoking {{predicate.getLiteralList}}. When evaluating {{BETWEEN}} operator in {{RecordReaderImpl::evaluatePredicateMinMax}}, it is possible to get {{IndexOutOfBoundsException}}. 
> Though exception is caught and skips PPD in {{pickRowGroups}}, it would be good to avoid this exception being generated too many times by having boundary checks.
