[Python] write_to_dataset(max_row_group_size)

[ryanhaarmann]

I converted from using pyarrow.dataset.write_dataset to pyarrow.parquet.write_to_dataset and noticed that this section of code is overwriting my max_row_group_size param to None. It seems it forces the user to pass in chunksize or row_group_size. I think an additional kwargs.pop would be necessary here.

arrow/python/pyarrow/parquet/core.py

Lines 2194 to 2196 in 71a7b55

	write_dataset_kwargs['max_rows_per_group'] = kwargs.pop(
	'row_group_size', kwargs.pop("chunk_size", None)
	)
