我的代码如下：星火：写入错误流文件/ XXX /标准错误产生java.io.IOException：流闭
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(_))
}
当我运行它作为本地模式，一切都是OK.However，当在集群中运行它，它会crash.I已经得到了以下错误消息：

真的很困惑这个，解决这个问题的好主意吗？ 我的集群环境是：Spark 1.5.1/hadoop 2.5.2/scala 2.10.4/jdk1.7.0_51。
你确定'sc.addJar（“/ home/found/FromWindows/testsSpark/out/artifacts/untitled_jar/untitled.jar”）'是文件的正确位置吗？您可以在Spark日志中看到它是否能够拿起驱动程序并将其发送给工作人员。 –
我相信这个位置是正确的。当调用RDD的collect（）在'val res = count.collect（）'时，代码崩溃了。 – KLordy
那是因为RDD正在实现的时候。 –
