[jira] [Created] (PARQUET-362) Parquet buffered writer is too sensitive regarding unions and unknown fields

Laurent Goujon created PARQUET-362:
--------------------------------------

             Summary: Parquet buffered writer is too sensitive regarding unions and unknown fields
                 Key: PARQUET-362
                 URL: https://issues.apache.org/jira/browse/PARQUET-362
             Project: Parquet
          Issue Type: Bug
          Components: parquet-mr
    Affects Versions: 1.8.0, 1.7.0, 1.8.1
            Reporter: Laurent Goujon


Parquet does prevent records with unknown union fields to be written as it would create a TProtocol violation. But it also prevents records with unions having one their field itself having an unknown field (which is acceptable if it is a struct).

The recursive check should be removed, and only when a union field is unknown should the record be deemed invalid.
