> Upgrading ORC reader version
> ----------------------------
>
> Key: TAJO-2052
> URL: https://issues.apache.org/jira/browse/TAJO-2052
> Project: Tajo
> Issue Type: Improvement
> Components: Storage
> Affects Versions: 0.11.0
> Reporter: Jongyoung Park
> Assignee: Jongyoung Park
> Priority: Minor
>
> Currently Tajo uses presto-orc-0.86, but it was old version even when it was
> integrated because Presto was using JDK 1.8 at that time.
> Now that Tajo is based on JDK 1.8, it can be upgraded to a recent version
> 0.132.
> It becomes more robust and some minor features are added.
> Additionally hive compatibility is improved, so upgrading is necessary to
> support Hive-catalog.
