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

             Summary: [C++] Add union support in ORC reader & writer
                 Key: ARROW-11118
                 URL: https://issues.apache.org/jira/browse/ARROW-11118
             Project: Apache Arrow
          Issue Type: New Feature
            Reporter: Ying Zhou


Currently the ORC reader does not has support for the ORC UNION type which led to the ORC writer to be under-tested for ORC DENSE_UNION and SPARSE_UNION types. To fix this problem union support in the ORC reader needs to be added, union support in the ORC writer needs to be added and tested.
