The authenticity of host '172.16.33.53 (172.16.33.53)' can't be established的问题(日志六)
用ssh登录一个机器(换过ip地址)会出现如下错误 weiguohui@weiguohui1-virtual-machine:~/.ssh$ ssh 172.16.33.53 The authenticity of host '172.16.33.53 (172.16.33.53)' can't be established. ECDSA key fingerprint is 28:17:f7:c3:58:54:fb:6e:dd:b9:61:61:c4:8a:45:0f. Are you sure you want to continue connecting (yes/no)? Host key verification failed. 导致我的secondenamenode 和datanode 无法启动,最后通过查资料解决,是解决的方法为: weiguohui@weiguohui1-virtual-machine:~/.ssh$ ssh -o StrictHostKeyChecking=no 172.16.33.53 然后再ssh 登录就不会报错了 来源: https://www.cnblogs.com/beigongfengchen/p/5464669.html
