viirya commented on issue #23719: [SPARK-26808][SQL] Pruned schema should not 
change nullability
URL: https://github.com/apache/spark/pull/23719#issuecomment-459625828
 
 
   I'm reusing it when prototyping schema pruning in other place (not parquet), 
so I found this bug. Given the inputs to the method, it is correct to keep the 
nullability of input data type. I opened this as a separate fix. If others also 
think this should not be fixed, I will close it and include it when I finish 
the prototyping.
