> If we call [GroupedIterator|https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/GroupedIterator.scala]'s {{hasNext}} immediately after its {{next}}, we will generate an extra group ([CoGroupedIterator|https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/CoGroupedIterator.scala] has this behavior).
