------------------------------------------

             Summary: Bad seek in uncompressed ORC, at row-group boundary.
                 Key: HIVE-9471
                 URL: https://issues.apache.org/jira/browse/HIVE-9471
             Project: Hive
          Issue Type: Bug
          Components: File Formats, Serializers/Deserializers
    Affects Versions: 0.14.0
            Reporter: Mithun Radhakrishnan

Under at least one specific condition, using index-filters in ORC causes a bad seek into the
ORC row-group.
