我是按照这里和这里的指示做的。
所有的网址都被正确打开，然后我试着运行wordcount示例。我进入了被接受的状态。。没有跑。

[root@localhost hadoop-2.6.0]# yarn jar /usr/local/deployment/WordCount.jar input output

web界面上的以下输出：

User:   root
Name:   wordcount
Application Type:   MAPREDUCE
Application Tags:   
State:  ACCEPTED
FinalStatus:    UNDEFINED

有人能告诉我可能的原因吗？？
