当我输入 时hadoop fs -ls，我收到以下错误消息：
deepak@deepak:~$ hadoop fs -ls
14/03/19 12:18:52 INFO ipc.Client: Retrying connect to server: localhost/127.0.0.1:9000. Already tried 0 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1 SECONDS)

hadoop namenode -format 的输出是
deepak@deepak:~/programs/hadoop-1.2.0/bin$ hadoop namenode -format
