Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:adqH907amvyYtAc7evqtYRcH/9Aovmz3sgY9Go6dmho.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.

解决方法：

编辑文件/root/.ssh/known_hosts ，注释掉hadoop01行，保存退出。重新执行 ssh hadoop01命令，按提示录入密码即可。
