这似乎是在使用SSH连接时出现的警告消息。它指出您尝试连接的主机不在已知主机列表中,因此连接将被拒绝,直到您将其添加到已知主机列表中。建议您将主机添加到已知主机列表中,以避免此警告消息。您可以执行以下命令将主机添加到已知主机列表中:
```
ssh-keyscan -t rsa <hostname> >> ~/.ssh/known_hosts
```
其中,`<hostname>` 是您要连接的主机的主机名或IP地址。执行此命令后,再次连接主机时,您应该不会再收到该警告消息。

mv: cannot stat './hadoop-3.1.3/': No such file or directory
This error message indicates that the file or directory specified in the command "mv ./hadoop-3.1.3/" does not exist in the current directory.
There could be several reasons for this error, such as:
- The file or directory was deleted or moved to a different location.
- There was a typo in the command or the file/directory name.
- The user does not have the necessary permissions to access the file/directory.
To resolve this error, you can try the following steps:
1. Check the spelling and path of the file/directory in the command. Make sure it exists in the current directory or specify the correct path to the file/directory.
2. Verify that you have the necessary permissions to access the file/directory. Use the command "ls -l" to check the file permissions and ownership.
3. If the file/directory was moved or deleted, try to locate it or restore it from a backup.
Once you have resolved the issue, you can retry the "mv" command.
