Is there a way to create or convert a pair RDD from one type to another.



Example :



if we wanted to convert



JavaPairRDD<String, Double> to JavaPairRDD<Integer, Double>



here the task is just to change the type of the key.

          U can convert like below



          JavaRDD<String> words = sc.parallelize(Arrays.asList("1","2"));
          

          
JavaPairRDD<String, Double> pairRDD = words.mapToPair(s -> new Tuple2<>(s, 1.0));
          

          
JavaPairRDD<Integer, Double> pairRDD1 = pairRDD.mapToPair(f->new Tuple2<>(Integer.parseInt(f._1), 1.0));
