  我也遇到了和楼上相同的问题，少了两个进程

  同时，运行 hadoop fs -ls /的时候显示以下错误

  ls: Call to ubuntu/127.0.1.1:9000 failed on connection exception: java.net.ConnectException: Connection refused

  不知道应该怎样更改配置文件，求解

  （我的localhost的名字是ubuntu）

  配了好久解决了上个问题，现在每步操作都做好了，但看JPS只有这几个东西。。

  root@ubuntu:/home/sd1700092/skyone/hadoop-1.2.1/bin# jps

  6501 SecondaryNameNode

  6906 Jps

  6312 DataNode

  6785 TaskTracker

  请问另外几个去哪里了？该怎么设置才能也出来，谢谢

  我去安装sudo apt-get install openssh-server时接着报错，

  Reading package lists... Done

  Building dependency tree       

  Reading state information... Done

  Some packages could not be installed. This may mean that you have

  requested an impossible situation or if you are using the unstable

  distribution that some required packages have not yet been created

  or been moved out of Incoming.

  The following information may help to resolve the situation:

  
  

  The following packages have unmet dependencies:

   openssh-server : Depends: openssh-client (= 1:5.9p1-5ubuntu1.3) but 1:5.9p1-5ubuntu1.4 is to be installed

                    Recommends: ssh-import-id but it is not going to be installed

  E: Unable to correct problems, you have held broken packages.

  
  

  这个又该怎么解决。。。？
