我無法運行start-dfs.sh無法運行start-dfs.sh

[email protected]:~$ start-dfs.sh

我做了安裝時的hadoop如下：

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

看來你有一個防火牆，防止遠程SSH連接。你檢查過'iptables'嗎？ – alvits 2014-10-20 07:03:36

您是否將默認SSH端口修改爲端口22以外的其他端口？ – skyjacks 2014-11-03 20:19:11

是否ssh localhost工作？我猜不會。你必須先做好這項工作。你必須有公鑰/私鑰集合的工作組合。欲瞭解更多信息，谷歌passwordless SSH login或看看這裏的例子：http://rcsg-gsir.imsb-dsgi.nrc-cnrc.gc.ca/documents/internet/node31.html
