While installing MapR Converged Data Platform, it is asking to configure the remote authentication. What details we need to mention in SSH Username and SSH Password?
You need to provide a username and either a Password or an SSH Private key for a user that has administrative access on every node that will have MapR installed. The MapR installer will use that account to perform the actual installation tasks.
Administrative access means, we need to give the user as root and its password
A user with root permissions, yes. Generally root itself can't SSH (and doesn't have a password).
