SYMPTOM: When you create an Oozie workflow which contains a SSH function, it can fail with an error of "Not able to perform operation [ssh -o PasswordAuthentication=no -o KbdInteractiveDevices=no -o StrictHostKeyChecking=no -o ConnectTimeout=20 root@localhost mkdir -p oozie-oozi/0000009-131023115150605-oozie-oozi-W/Ssh--ssh/ ] | ErrorStream: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)."

ROOT CAUSE: Passwordless SSH must be setup correctly from oozie@server1 to $user@server2
For example:

RESOLUTION:
If an Oozie workflow contains an ssh command from server 1 to server 2 as root, then the passwordless SSH must be setup as the following:

oozie@server1 > root@server2
