我正在使用eclipse/maven创建一个jar并在emr上运行它
这是我的pom.xml文件

这就是我在emr集群中部署和运行jar的方式
spark-submit --deploy-mode cluster --class financialLineItem.FinancialLineItem s3://path/SparkApplication-SQL-jar-with-dependencies.jar
当我在齐柏林飞艇笔记本上运行我的代码时,它运行得很好,但是 spark-submit
它抛出以下异常
Exception in thread "main" java.lang.ClassNotFoundException: financialLineItem.FinancialLineItem
我的项目设置是这样的:
如何纠正?
此外,我也遵循以下文件创建Spark和提交电子病历https://docs.aws.amazon.com/emr/latest/releaseguide/emr-spark-submit-step.html 在这里,它们既不是在spark作业配置中设置主url,也不是在从spark提交时设置主url
2条答案
按热度按时间tvokkenx1#
当您在集群模式下运行spark submit时,所发生的事情是驱动程序运行在不同于客户机的机器上,因此您在spark submit脚本中提供的jar需要放置在驱动程序的类路径上,如this:-
因此,您可以尝试以下脚本:

你失踪了
sourceDirectory
在你的pom.xml
.根据maven文档的标准目录布局,默认
sourceDirectory
是src/main/java
既然你的项目结构src/main/scala
,未编译类。将此添加到生成配置下:
