Can I not need to setup passwordless ssh if I install ambari-agent manually on each node?

If you are doing manual install of ambari agents then you do not need passwordless ssh.

If you are doing manual registration then you don't need to setup passwordless ssh. Ambari needs passwordless ssh or root password only to bootstrap(install and configure) Ambari agents. You have already done that so no need to configure!

Hope this information helps 🙂

But nevertheless its good practice to have password less connection between the nodes.Incase you use pdsh or other cluster management tools it makes life easier !!!
