~ gpadmin$ gpssh-exkeys -h localhost

Solution: create/copy the public key for gpadmin into an authorized_keys file and you performed the same thing gpssh-exkeys does; for a small test environment it's not a big deal but the tool comes in handy when exchanging keys across numerous nodes. That's all it does??? The authorized_keys file gets updated before it kicks out the error.
