> Key: ORC-221
> URL: https://issues.apache.org/jira/browse/ORC-221
> Project: ORC
> Issue Type: Improvement
> Reporter: Rajesh Balamohan
> Priority: Minor
>
> 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.
