localhost没有登录成功，应该是要安装ssh-server。
sudo apt-get install openssh-server
ssh localhost #登录，会要你输入密码
exit #退出当前登录
cd ~/.ssh/ #如果没有此目录，要先ssh localhost
ssh-keygen -t rsa #生成一个密钥
cat ./id_rsa.pub >> ./authorized_keys #密钥放入授权中做完以上步骤之后再ssh localhost，此时不用输入密码了
如果都不行，请去hadoop/logs下看日志。

是你的hadoop.env.sh这个配置文件有问题，
如果你的配置没问题，可能是你没有source，虽然不知道为什么每次启动都要source这个配置文件。你试试，我开始遇到这个问题就是这样解决的 -
