URL: https://github.com/apache/spark/pull/23900
 
 
   ## What changes were proposed in this pull request?
   
   This change adds support for returning StructType from a scalar Pandas UDF, where the return value of the function is a pandas.DataFrame. Nested structs are not supported and an error will be raised, child types can be any other type currently supported.
   
   ## How was this patch tested?
   
   Added additional unit tests to `test_pandas_udf_scalar`
