Question

这个问题之前被问过几次，我尝试了所有建议的解决方案来生成无密码密钥，但无济于事。可能需要做一些与从 VM Fusion 在 Ubuntu 上执行此操作不同的事情？

hadoop@ubuntu:~$ start-dfs.sh
Starting namenodes on [localhost]
localhost: hadoop@localhost: Permission denied (publickey,password).
Starting datanodes
localhost: hadoop@localhost: Permission denied (publickey,password).
Starting secondary namenodes [ubuntu]
ubuntu: hadoop@ubuntu: Permission denied (publickey,password).

考虑到您需要在本地主机上自行复制“hadoop”用户密钥

类似：

sudo su hadoop
ssh-keygen
ssh-copy-id hadoop@localhost

那你可以试试：

sudo su hadoop 
ssh hadoop@localhost

在“start-dfs.sh”之后出现错误“权限被拒绝（公钥，密码）”
