> There are some weird issues with exploding Python UDFs in SparkSQL.
> There are 2 cases where based on the DataType of the exploded column, the 
> result can be flat out wrong, or corrupt. Seems like something bad is 
> happening when telling Tungsten the schema of the rows during or after 
> applying the UDF.
> Please check the attached notebook for reproduction.
