> With recent HEAD, unable to create or killall job. It always complain following error:

> aurora create cp0/bhuvan/staging10/hello hello_world.aurora              [stories/apps-in-docker] 15:35:57
>  INFO] Creating job hello
>  INFO] Starting new HTTP connection (1): a005832.vp.iso.apple.com
>  INFO] Starting new HTTP connection (1): a005832.vp.iso.apple.com
>  INFO] Response from scheduler: LOCK_ERROR (message: Unable to perform operation for: bhuvan/staging10/hello. Use override/cancel option.)
>  INFO] 
> Note: if the scheduler detects that a job update is in progress (or was not
> properly completed) it will reject subsequent updates.  This is because your
> job is likely in a partially-updated state.  You should only begin another
> update if you are confident that nobody is updating this job, and that
> the job is in a state suitable for an update.
> After checking on the above, you may release the update lock on the job by
> invoking cancel_update.
> {code}
> The scheduler log, when run in FINE log level, show that one lock is held. The lock is held by completely different task. Confirmed it by querying {{/locks}} endpoint. This is the commit, where lockMapper is changed to use {{LEFT OUTER JOIN}}.
