Hello all, I'm trying to install a Hadoop cluster with Ambari on one VM and two additional nodes that will serve as a hadoop cluster. On step 2, where it says to add nodes, I select the id_rsa.pub file for the user I'm running the install with, let's call it hduser. I already copied the ssh keys to all machines and setup passwordless ssh to each and all machines. I also select /etc/hosts file that has all three VMs. When I hit next, it fails for some or all of the machines. I then created another file called hosts, containing the names of only two machines participating in a hadoop cluster, excluding the Ambari server. The add nodes step fails again due to permission denied again. It does, still include my Ambari server as the 3rd server to install hadoop on. Is there anything that I'm doing wrong?
