@hvanhovell Thanks for the hint. I am trying it. However this listener
would be in operators case by case, e.g., HashAggregate here. If there are any
other operators needed to release resources after all rows iterated, we may
need to add similar listeners too.
Originally I am little worrying the possible performance regression due to
extra consuming of row. With task completion listener, this is not an issue.
