Question

我在我的Ubuntu 14.04上安装了hadoop 2.7.1。在我运行jps命令后安装它显示了以下内容：

sukalyan @ sukalyan-Lenovo-G50-80：〜$ jps

7601 NodeManager

7464 ResourceManager

7921 Jps

7292 SecondaryNameNode

7099 DataNode

可以清楚地看到namenode缺失，因此当我在浏览器上运行localhost：50070时，它显示“问题加载页面”。我经历了很多解决方案，但不幸的是它们都没有工作。可能是错的，如何让namenode运行？谢谢

Answer 1

最初我的localhost设置为9000，我认为由于某种原因已经占用了。我将它更改为另一个位置54310，现在我的名字节点似乎像奇迹一样工作！
