MapR Installer permission error

I am using MapR install script for the new 3.1.0 install, starting a simple case of a single node which is identified by its actual hostname (not localhost). I am getting a permissions error with somewhat unclear cause/message.

Here is the log of the interactive session -

Could you help clarify how a local node could be unreachable? I do not yet have SSH authentication set up between the nodes, but should it really be necessary for the local node (even though not identified as localhost/

Is there anything that should be done for ansible configs, per the message? I am not seeing ansible.cfg anywhere...

P.S. SSH login/password entered here were correct for the local node. Shouldn't this be enough to authenticate?
