su root

gedit /etc/sudoers
ram ALL =(ALL) NOPASSWD: ALL

error 2:
Installation failed.Failed to receive heartbeat from agent.
Ensure that the host's hostname is configured properly.
Ensure that port 7182 is accesible on the Cloudera Manager server (check firewall rules).
Ensure that ports 9000 an 9001 are free on the host being added.

fix:

/etc/hosts was looking like this when I had the problem
127.0.0.1 localhost
127.0.1.1 ubuntu

I changed it like this:
127.0.0.1 localhost
127.0.0.1 ubuntu
