Error Message
SSH already configured
If root does not have password-less you will be prompted three times for each host
Explanation
This error occurs when using install_vertica. It indicates that ssh is already configured for root so that each connection requires a password.
Workaround
It is possible that dba-ssh-config succeeded. Log in to the administrative account and test ssh by connecting to each other host. If unsuccessful, log in to the console on each host and perform the Enable Secure Shell (SSH) Logins procedure in the Installation Guide.
