当我按照 http://blog.csdn.net/xichenguan/article/details/38796541 这个文章的提示，讲yarn-site中的最后一项yarn.application.classpath 注释掉后，错误的提示改为

发现根本就不是那么一回事，这种该法不适合这个问题
打开提示的网页
想通过查看日志文件，看看问题的所在，虽然提示的内容类似，但是实际上真实的问题所在是不一样的，只有通过日志文件才能够看到到底哪里出现了问题

网页无法访问的原因是所有的地址都是相对于NameNode来说的，就是服务器来说的，在本地访问是访问不了的，即使你改成相对应的电脑的IP也是无法访问的，所以需要在本地安装一个Xming，和SSH Secure Shell绑定后就可以使用了
在shell中输入firefox,之后打开远程访问的浏览器
这样就可以查看错误的log文件了
查看错误内容为
师兄发现是jobhistory有问题，IO的问题，这个程序在原来的虚拟机中是可以运行的，但是之后不能使用，应该是权限的问题，或者配置的问题，后来发现是Jobhistory地址有问题，
参考：https://issues.apache.org/jira/browse/MAPREDUCE-5721
原来mapreduce.jobhistory.address 和mapreduce.jobhistory.webapp.addres 这两个address的地址使用的是CDH默认的配置值，这里需要改成hostname，这样可能就是原来的位置不对造成的
