Review Comment:
**I forgot to add the original comment here, will add in next revision**
But simple reason for this is that callbacks are asynchronously called

> DynamicScalingYarnService currently doesn't handle scaling down containers
> and neither does anything if container is killed abruptly or goes OOM. So to
> handle this scenario containerCompletion callback should be implemented to
> launch the replacement containers and also scaling down handling should be
> done.
