Description

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.
