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!
