/stop-all.sh
no jobtracker to stop
The authenticity of host 'localhost (::1)' can't be established. RSA key fingerprint is
Are you sure you want to continue connecting (yes/no)? yes 
localhost: Warning: Permanently added 'localhost' (RSA) to the list of known hosts.
localhost: Permission denied (publickey).
no namenode to stop
localhost: Permission denied (publickey).
localhost: Permission denied (publickey).

关于如何重启 hadoop 有任何想法吗？
