Question

我正在尝试在我创建的jar文件上运行spark-submit。当我在我的机器上本地运行它时它可以正常工作，但是当部署到Amazon EC2上时，它会返回以下错误。

root@ip-172-31-47-217 bin]$ ./spark-submit --master local[2] --class main.java.Streamer ~/streaming-project-1.0-jar-with-dependencies.jar

Answer 1

启动spark-ec2时，默认的hadoop版本为1.2.1。但是，最近的Spark版本（至少1.5.1）需要在Hadoop 2 +中引入的hadoop.fs.FileSystem类中的SHUTDOWN_HOOK_PRIORITY字段。

解决此问题的一个方法是使用Hadoop版本2+启动您的spark群集。有关可用选项，请参阅spark-ec2 --help。示例：--hadoop-major-version=yarn将安装Hadoop版本2.4。
