> 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: 1.7.0, 1.8.0, 1.8.1
> Reporter: Laurent Goujon
> Fix For: 2.0.0
>
>
> 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.
