I am trying to ssh into a remote machine and I get the following debug messages:
debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options
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
/home/hadoop/.ssh/id_rsa
/home/hadoop/.ssh/id_rsa.bak
