Spark - sort by value with a JavaPairRDD

Question

Working with apache spark using Java. I got an JavaPairRDD<String,Long> and I want to sort this dataset by its value. However, it seems that there only is sortByKey method in it. How could I sort it by the value of Long type?

Answer 1

dataset.mapToPair(x -> x.swap()).sortByKey(false).mapToPair(x -> x.swap()).take(100)
