--------------------------------------
cc [~bryanc] FYI. Does Arrow support null type?

> Key: SPARK-33489
> URL: https://issues.apache.org/jira/browse/SPARK-33489
> 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.
