我试图在伪分布式模式下安装Hadoop 2.2.0.当我尝试启动datanode服务时,它显示以下错误,任何人都可以告诉如何解决这个问题？

at**** …我正在尝试使用vmware工作站在我的笔记本电脑中配置一个主机和两个从机的hadoop-1.0.3多节点集群.
当我从master 运行start-all.sh时,在主节点(namenode,datanode,tasktracker,jobtracker,secondarynamenode)中运行的守护进程,但是Datanode和tasktracker没有在slave节点上启动.密码少ssh已启用,我可以从没有pwd的masternode为主服务器和从服务器执行ssh.
请帮我解决这个问题.
