从IntelliJ IDEA在YARN上运行Apache Spark程序

Question

我已经设置Apache Spark 1.1.1在YARN(Hadoop-2.5.2)上运行.我可以使用该spark-submit命令运行程序.

我正在使用IntelliJ IDEA 14.我能够使用构建工件并运行生成的jar spark-submit.

但是,我想知道是否可以直接从IntelliJ运行整个程序？

我添加了必要的库并激活了hadoop-2.4配置文件.但是,我最终得到以下错误

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.hadoop.security.UserGroupInformation.getCredentials()Lorg/apache/hadoop/security/Credentials;

谁能告诉我哪里出错了？

Answer 1

在 Intellij 中，您必须添加依赖项，它是 Hadoop conf 目录的路径

转到项目设置并在依赖项中添加路径 $HADOOP_HOME/etc/hadoop

如果您使用任何 lambda，则从项目设置 -> 源 -> 语言级别设置 8-lambda 类型注释
