Hi I want to send two value to the ConvergenceCriterion function, so i decided to use an aggregator of Tuple2. But then, when i implement Aggregator<Tuple2>, i cannot do that because Tuple2 doesn’t implement Value. So i tried to create a class Tuple2Value that implements Value, but here i get stuck because i don’t know how to do it in a proper way. Any suggestions? Is there an alternative (and easy) way to pass two values to the convergenceCriterion function?
Thank you Riccardo!
