Hope you are doing well,
Please try the command given below for password less ssh login:
1) Create ssh key on all the nodes first
ssh-keygen -t rsa -P ""
2) Copy the public key to the authorized_keys [ For all nodes]
cat /home/ubuntu/.ssh/my-aws-key-pair.pem >> /home/ubuntu/.ssh/authorized_keys
3) Copy the public key of master node to all other nodes
ssh-copy-id -i /home/ubuntu/.ssh/my-aws-key-pair.pem ubuntu@destination_node_host_name
