Per the doc: you need passwordless sudo not passwordless ssh.
Did you enter the username and password when adding the host to cloudera manager?
https://docs.cloudera.com/cdp-private-cloud-base/7.1.8/managing-clusters/topics/cm-add-hosts.html
Enter Login Credentials:
Select root for the root account, or select Another user and enter the username for an account that has password-less sudo privileges.
Select an authentication method:
If you choose password authentication, enter and confirm the password.
If you choose public-key authentication, provide a passphrase and path to the required key files.
You can modify the default SSH port if necessary.

I'm setting up a single-node Cloudera Manager 7.4.4 trial on a GCP Ubuntu 20.04 VM and running into an issue during the Install Agents step. The process fails with an authentication error when trying to connect to the host.
Here’s what I’ve done so far:
Created a user with sudo and passwordless privileges
Set up passwordless SSH (tested with ssh $(hostname -I | awk '{print $1}') – works without password)
Configured hostname and /etc/hosts (e.g., cloudera-1.localdomain)
Installed OpenJDK 11 and set JAVA_HOME
Started Cloudera Manager Server successfully (systemctl status shows it running)
Port 7180 is open and accessible
Using the .bin installer from the official CM 7.4.4 archive
Despite all this, the agent install step fails with an authentication error. Has anyone encountered this before? Is there a specific SSH or hostname nuance I might be missing?
Any help would be greatly appreciated!
