Parity with vanilla PySpark.

Yes. `DataFrame.mapInArrow` is supported as shown below.

>>> def filter_func(iterator):
... for batch in iterator:
... pdf = batch.to_pandas()
... yield pyarrow.RecordBatch.from_pandas(pdf[pdf.id == 1])
...
>>> df.mapInArrow(filter_func, df.schema).show()
+---+---+
| id|age|
