hdfs连接失败

Question

我知道这个问题已经讨论了很多次，但没有一个解决方案适合我。我仍然收到此错误。

hadoop版本是2.0.2-alpha

$ jps
24107 NameNode
24314 DataNode
25299 Jps
24720 NodeManager
24520 ResourceManager

$ hdfs dfs ... any command gives me this error 
<command>: Call from jeet/192.168.1.26 to jeet:9000 failed on connection exception: java.net.ConnectException: Connectionrefused;
