Jay Buffington commented on AURORA-1056:

Ah, I hadn't seen AURORA-1014.  I agree that is a better idea.  Thanks!

> mesos 0.21 introduced "force_pull_image" which IMHO, is a terrible idea and changed existing
> In 0.20 the image you specify will always be "docker pull"ed which means that if there
was a newer version in the registry than the one in the cache you would get it.  
> After 0.21 force_pull_image defaults to false, so unless you make a code change the "docker
pull" doesn't happen.  This means that if your cache has an older copy of the image, you run
whatever happens to be in the cache.  
> This results in starting 5 instances of the job, and 3 might one the old version (because
it was cached on that slave) and 2 might one the new version (because those two slaves didn't
have it cached), which is never what users want.
