      Description

      It would be great to support MapType and (nested) StructType in Arrow so that PySpark can make use of it.

       
      Quite often as in my use-case in Hive table cells are also complex types saved. Currently it's not possible to user the new pandas_udf decorator which internally uses Arrow to generate a UDF for columns with complex types.
