Я новичок в Spark, установил Spark на мой компьютер с Windows и выполняю команду spark в spark-shell.Создано просто RDD и найти нет.раз текст встречается.вот мой блок кода.это вызывает FileNotFound Exception.
scala> val inputrdd = sc.parallelize{ Seq("a", "b", "c", "d","a","a") }
inputrdd: org.apache.spark.rdd.RDD[String] = ParallelCollectionRDD[70] at parallelize at <console>:24
scala> inputrdd.count
res102: Long = 6
scala> inputrdd.first
res103: String = a
scala>
scala> inputrdd.countByValue()
