Spark上SimRank算法的实现

package main.scala
import org.apache.spark._
import SparkContext._
object SparkSimRank {
  def main(args: Array[String]) {
    val iters = 10
    val conf = new SparkConf()
             .setMaster("local")
             .setAppName("PagRank")
             .set("spark.executor.memory", "1g")
             .setSparkHome("/home/wang/spark-0.9.0")           //(System.getenv("SPARK_HOME"))
             .setJars(Seq(System.getenv("SPARK_TEST_JAR")))
    val cs = new SparkContext(conf)
    val simrankline = cs.textFile("/home/wang/Desktop/experiment/input/5")
    val graphline = cs.textFile("/home/wang/Desktop/input/5")
    val indegreeline =
