Roee Shlomo created ARROW-14179:
-----------------------------------

             Summary: [C++] Import/Export of UnionArray in C data interface has wrong buffer count
                 Key: ARROW-14179
                 URL: https://issues.apache.org/jira/browse/ARROW-14179
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Roee Shlomo


The C Data Interface implementation for UnionArray includes a validity buffer as the first buffer. However, union arrays should have no validity buffer according to the specification ([Arrow Columnar Format — Apache Arrow v5.0.0|https://arrow.apache.org/docs/format/Columnar.html#buffer-listing-for-each-layout])
