Jesus Camacho Rodriguez commented on HIVE-14381:
------------------------------------------------
+1, I was checking the code, and the change makes sense, although we should
still call {{output.set(j, out);}} in every case, as stated above.
We make a similar conversion to NULL value in two other places; it seems like
it was forgotten to do it in the {{next()}} method too.
> Handle null value in WindowingTableFunction.WindowingIterator.next()
