我是spark&scala新手，调用saveastextfile（）后出现异常。希望有人能帮忙。。。
这是我的input.txt：

Hello World, I'm a programmer 
Hello World, I'm a programmer

这是在cmd上运行“spark shell”后的信息：

C:\Users\Nhan Tran>spark-shell
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
Spark context Web UI available at http://DLap:4040
Spark context available as 'sc' (master = local[*], app id = local-1526374303208).
Spark session available as 'spark'.

scala>

这是我的密码：

scala> val inputfile = sc.textFile("input.txt")
scala> val counts = inputfile.flatMap(line => line.split(" ")).map(word => (word, 1)).reduceByKey(_+_);
scala> counts.toDebugString
scala> counts.cache()
scala> counts.saveAsTextFile("output")

在调用counts.saveastextfile（“output”）之前，一切正常，以下是我的例外：

从错误日志中。好像你在windows上使用spark。您可以尝试以下故障排除steps:-
搜索winuntils.exe路径
cd路径
winutils.exe chmod 777输出（存储输出的目录）
让我们再次尝试存储输出( counts.saveAsTextFile("output") )

我认为您需要正确指定输入文件路径。您的输入rdd没有被创建，这就是为什么它不能创建输出。
你应该看到below:-

scala> val inputfile = sc.textFile("file:///home/lg552987/input.txt")

inputfile: org.apache.spark.rdd.RDD[String] = file:///home/lg552987/input.txt MapPartitionsRDD[5] at textFile at <console>:27

scala> val counts = inputfile.flatMap(line => line.split(" ")).map(word => (word, 1)).reduceByKey(_+_)

counts: org.apache.spark.rdd.RDD[(String, Int)] = ShuffledRDD[8] at reduceByKey at <console>:29

scala> counts.toDebugString

res0: String =
(2) ShuffledRDD[8] at reduceByKey at <console>:29 []
 +-(2) MapPartitionsRDD[7] at map at <console>:29 []
    |  MapPartitionsRDD[6] at flatMap at <console>:29 []
    |  file:///home/lg552987/input.txt MapPartitionsRDD[5] at textFile at <console>:27 []
    |  file:///home/lg552987/input.txt HadoopRDD[4] at textFile at <console>:27 []

scala> counts.cache()

res1: counts.type = ShuffledRDD[8] at reduceByKey at <console>:29

scala> counts.saveAsTextFile("output")
