The command to stop a compare is
sp_ctrl> cancel job_id
sp_ctrl (avrstones:8606)> compare using chainer_local.conf
comparing 1 of 1 objects
compare started; job id 5
sp_ctrl (avrstones:8606)> show compare
The syntax to get status for the compare command has changed
Instead of 'show compare' use the 'compare status' or 'repair status' command
