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 中得到的错误信息:

最佳答案
我在我的 mac 上尝试安装 hadoop 时遇到了同样的异常，我通过在 yarn-env.sh 和 hadoop-env.sh 文件中显式定义 java home 解决了这个问题
因此转到 etc/hadoop 并使用显式 java 主目录编辑 hadoop-env.sh 和 yarn-env.sh 文件。
导出 JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk...
祝你好运!
关于hadoop - 无法在 eclipse 中运行 TestDistributedShell，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21275735/
