Can you elaborate please?

Hi, In my code, I set the number of reducers to 1, conf.setNumReduceTasks(1); and it all works as intended, but I notice that the reducer is called a second time to do nothing, before all is done. Can I use this side effect to close the static resources (like a zip output stream) that I open on the first call? Thank you, Mark
