我做了安装时的hadoop如下：

ssh-keygen -t rsa -P '' 
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

看来你有一个防火墙，防止远程SSH连接。你检查过'iptables'吗？ – alvits 2014-10-20 07:03:36

您是否将默认SSH端口修改为端口22以外的其他端口？ – skyjacks 2014-11-03 20:19:11

是否ssh localhost工作？我猜不会。你必须先做好这项工作。你必须有公钥/私钥集合的工作组合。欲了解更多信息，谷歌passwordless SSH login或看看这里的例子：http://rcsg-gsir.imsb-dsgi.nrc-cnrc.gc.ca/documents/internet/node31.html
