我尝试部署了一个测试hadoop集群环境。当我启动它时，所有日志都正确，但是无法运行任何hadoop命令，我发现9000端口没有被监听。

运行hadoop命令(ERROR，所有命令都是一样的错误):

hadoop-2.5.0/bin$ ./hdfs dfs -ls /
14/08/15 10:19:52 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
ls: Call From master-hadoop/172.17.65.225 to master-hadoop:9000 failed on connection exception: java.net.ConnectException: Connection refused; For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused

Namenode 9000端口没有被监听

hadoop-2.5.0/bin$ sudo netstat -ntap | grep 9000
Terminal console doesn't output anything.
