What seems to be the problem?? I have tried everything, this is driving me nuts.

You say that you are having trouble with a "new" node, however, there seems to be an entry for that ip in ~/.ssh/known_hosts It seems likely that it is trying to use the setup from a previous session. You say that you copied id_rsa, but you should have tried moving it to prevent it from being found and used. You can see the file mentioned in your post, particularly the line " Offering public key: /home/hadoop/.ssh/id_rsa"

Try moving both of those files (id_rsa and known_hosts) and see if that changes things.

Looks like a bad private key. I would start by moving /home/hadoop/.ssh/id_rsa to /home/hadoop/.ssh/id_rsa.bak and seeing if that helps anything

As the answer above states, it looks to be a bad key. Run ssh-keygen and create a new one with the existing one being backed up.

Then try doing an

id_rsa.pub >> authorized_keys

no copying/pasting. Copying/pasting from VIM can lead to user error.
