There are 1 datanode(s) running and no node(s) are excluded in this operation.错误
在编写jsp的时候发现这个问题，百度了良久之后发现这个问题在这个人的文档里给出了想当的解释，http://blog.sina.com.cn/s/blog_4c248c5801014nd1.html
一开始并没发现问题出在那，经过log查询发现了问题我的hadoop 的datanode竟然没启动。
于是我到／usr／local／hadoop/bin（hadoop安装目录）里开启strart-all.sh却发现我的datanode怎么启动不了了。
于是查看上面大神的文档才发现，我以前平凡的对ntfs进行过不正当的格式化导致的这种问题。
于是我到hadoop文件下吧htfs里的name文件删掉和tmp文件也删掉。
重新进行一次格式化hadoop namenode -format (不建议使用)
一直百度没找到正确的显示格式化正常的界面，但是我这次格式化成功，所有的东西都能启动，不知道这种是不是正确的格式化
正确格式化的代码如下
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.
