/** * Return a new RDD containing the distinct elements in this RDD. */defdistinct(numPartitions:Int)(implicit ord:Ordering[T]=null):RDD[T]=withScope{map(x=>(x,null)).reduceByKey((x,y)=>x,numPartitions).map(_._1)}//numPartitions:分区数 3.2 无参: 代码语言:javascript 代码运行次数...
val line: RDD[Int] = sc.parallelize(array,2) line.distinct().foreach(x => println(x)) //输出的结果已经去重:1,2,3,4 } } 通过上面的代码可以看出,使用distinct以后,会对重复的元素进行去重。我们来看下源码 /** * Return a new RDD containing the distinct elements in this RDD. */ def d...
