解决方案
解决方案二：
<name>yarn.nodemanager.aux-service</name>这个写错了，应该是：<name>yarn.nodemanager.aux-services</name>编码要认真啊。
解决方案三：
编码要认真啊。
解决方案四：
谢谢分享..........
解决方案五：
大神，我的配置没问题，也出现这个错误，请教。。。。
解决方案六：
解决方案七：
请问大神你是如何配置好的，我用之前旧的版本的搭建方式换到hadoop2.7上，各种不成功呢。请问主要要配置哪些文件？求解。。。。
解决方案八：
请问楼主你在修改yarn配置之后再怎么做呢，直接又运行一次hadoopjar/cloud/hadoop-2.7.0/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.0.jarwordcount/words/count呢，还是需要再重新格式阿虎集群呢
