[jira] [Created] (TAJO-2052) Upgrading ORC reader version

Jongyoung Park created TAJO-2052:
------------------------------------

             Summary: 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.
