    Description

      In Spark, we can invoke  Dataset method "queryExecution.debug.codegen()" to get the code produced by Catalyst.  If we add a similar API to enable user to get the code generated by 
      Flink engine, this would be a very nice way to provide more verbose feedback for debugging.
