我可以在 Maven 中成功运行 TestDistributedShell，但在 Eclipse 中失败。我需要做任何额外的设置吗？

这是我在 Eclipse 中收到的错误消息：

我在尝试在我的 Mac 上安装 hadoop 时遇到了同样的异常，我通过在 yarn-env.sh 和 hadoop-env.sh 文件中明确定义 java home 解决了这个问题

所以去 etc/hadoop 并使用明确的 java 主目录编辑 hadoop-env.sh 和 yarn-env.sh 文件。

导出 JAVA_HOME=/库/Java/JavaVirtualMachines/jdk...

祝你好运！
