--------------------------------------
Yes, Arrow supports null type. Should be pretty straightforward to add in Scala
and Python. Is this something you are interested in working on adding

> Project: Spark
> Issue Type: Improvement
> Components: PySpark
> Affects Versions: 3.0.1
> Reporter: Yuya Kanai
> Priority: Minor
>
> I got below error when using from_arrow_type() in pyspark.sql.pandas.types
> {{Unsupported type in conversion from Arrow: null}}
> I noticed NullType exists under pyspark.sql.types so it seems possible to
> convert from pyarrow null to pyspark null type and vice versa.
