import org.apache.spark.SparkContext
object wordcount
{
  def main(args: Array[String])
  {
    val inputPath =args(0)
    val outputPath = args(1)
    val sc = new SparkContext()
    val lines = sc.textFile(inputPath)
    val wordCounts = lines.flatMap{line => line.split(" ")}.map(word => (word, 1)).reduceByKey(_ + _)
    wordCounts.saveAsTextFile(outputPath)
    sc.stop()
  }
}

然后编译没问题，运行就出现下面这个问题
