Apache Spark多节点群集 - java.io.FileNotFoundException

时间：2015-11-25 19:34:13

标签： apache-spark

我是Apache Spark和Cluster Computing的新手，我在独立模式下实现Spark（与Master和Worker相同的机器），它对我来说很好。

然后，我下载了预构建的spark版本，并按照这些说明放置在我的群集的每个节点中：http://spark.apache.org/docs/latest/spark-standalone.html#installing-spark-standalone-to-a-cluster。

我的主节点有IP地址：172.17.0.224，我的从节点有IP地址：172.17.0.221,172.17.0.222和172.17.0.223。

我编辑了slaves和spark-env.sh文件，分别添加了我的从站的IP地址和我的主站的IP地址。

我启动了主节点start-master.sh并使用start-slaves.sh启动了从属节点，一切正常。

我使用命令spark-submit --class "Rice" --master spark://172.17.0.224:7077 cs453project/target/scala-2.11/simple-project_2.11-1.0.jar cs453project/input.txt cs453project/ouput2 cs453project/ouput3提交了我的spark-job。

这是我收到的错误消息：
