Spark：将流写入文件/ XXX / stderr java.io.IOException时出错：流已关闭

标签： apache-spark ioexception

我的代码如下：

object WordCount extends App{
  val conf = new SparkConf().setAppName("WordCount").setMaster("spark://sparkmaster:7077")
  val sc = new SparkContext(conf)
  sc.addJar("/home/found/FromWindows/testsSpark/out/artifacts/untitled_jar/untitled.jar")
  val file = sc.textFile("hdfs://192.168.1.101:9000/Texts.txt")
  val count = file.flatMap(line => line.split(" ")).map(word => (word,1)).reduceByKey(_+_)
  val res = count.collect()
  res.foreach(println(_))
}

当我以本地模式运行时，一切正常。但是，当在群集上运行时，它会崩溃。我收到以下错误消息：

真的很困惑，解决这个问题有什么好主意吗？    我的集群环境是：Spark 1.5.1 / hadoop 2.5.2 / scala 2.10.4 / jdk1.7.0_51。

2 个答案:

答案 0 :(得分：0)

我的猜测是sc.addJar("/home/found/FromWindows/testsSpark/out/artifacts/untitled_jar/untitled.jar")在您的执行程序上失败，因为执行程序节点上不存在该路径/ jar。尝试将jar放入HDFS并使用HDFS路径指定它，以便执行者可以访问它。

或者甚至更好，使用--jars spark-submit的{​​{1}}命令行选项并在那里指定jar，然后您就不必更改代码并重新填写更改您的jar。

答案 1 :(得分：0)

问题已经解决了。主要原因是我的项目导入了两个版本的scala（sbt下载的一个额外版本）。感谢帮助我解决这个问题的人。
