SSH登录时出现Warning: Permanently added告警问题解决方案

1.SSH启动Hadoop时

hadoop1: Warning: Permanently added 'hadoop1,192.168.xxx.xxx' (ECDSA) to the list of known hosts.

 

2.解决方案

　　创建 ~/.ssh/config 文件

vim ~/.ssh/config

　　在文中输入以下内容：

UserKnownHostsFile ~/.ssh/known_hosts

 

3.关闭 Hadoop，重新启动 Linux 系统后再次启动 Hadoop 即可。
