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

Do you enter that line in the workflow itself to set up passwordless SSH?

Can someone please elaborate more on how to set up passwordless SSH or embed into workflow? Thank you.
