Hi Riadh I'm not sure on the customization to achieve that goal, but it should be possible. But if your requirement is to output the same line n number of times as the map output, you don't need to go that way. Just call the outputCollector.collect() or context.write() within a loop in your map method. If you could post in your requirement then may be we can help you better.
