今天早上我用了hadoop2.4（见我前面的两个问题）。现在我删除了它并安装了2.2，因为我有2.4的问题，而且我认为2.2是最新的稳定版本。现在我在这里学习了教程：

我很肯定我做的每件事都是对的，但我又面临着类似的问题。
当我运行jps时，很明显数据节点没有启动。
我又做错什么了？
任何帮助都将不胜感激。

我的问题是，我把这些指导从教程太字面。
粘贴以下内容
<configuration>fs.default.name名称hdfs://localhost:9000
我怀疑这是错误的，但我还是做了。
这似乎是不正确的
core-site.xml文件为xml格式。所以实际上，它应该是这样的。
把它改成这个可以解决我的问题。

我在datanode没有启动时遇到了类似的问题。我所做的是重新格式化namenode，然后重新启动集群。然后，跑步
jps确认数据节点已启动。这可能是由于将hdfs目录放在“主”目录（在linux框上）中造成的，因为在启动和关闭操作系统时，操作系统会影响这些文件夹（不完全确定如何影响，但为了防止将来出现此问题，请将hdfs目录移出主目录）。
请让我知道这是否有效。
