Hi Sree
I dont think what you are trying to do is correct. DataFrame and ResultSet are two different types. And no strongly typed language will alow you to do that.
If your intention is to traverse the DataFrame or get the individual rows and columns then you must try the map function and pass anonymous function definitions with the required logic.
thanks
rakesh
