[jira] [Created] (ARROW-15496) [Python] Log warning when user tries to write parquet table with incompatible type

Grant Williams created ARROW-15496:
--------------------------------------

             Summary: [Python] Log warning when user tries to write parquet table with incompatible type
                 Key: ARROW-15496
                 URL: https://issues.apache.org/jira/browse/ARROW-15496
             Project: Apache Arrow
          Issue Type: Wish
          Components: Parquet, Python
            Reporter: Grant Williams


Could we get a logged warning when a user tries to `pyarrow.parquet.write_table()` with `version=1.0` and a schema that contains an incompatible `uint32()` type? I don't think the behavior to upcast to an `int64()` is immediately obvious (although the docs are clear on it) and I think it would help prevent some confusion for other users.
