> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler
> Affects Versions: 0.23.3
> Reporter: Thomas Graves
> Assignee: Arun C Murthy

>
> The capacity scheduler has the ability to 'reserve' containers.
> Unfortunately before it decides that it goes to reserved rather then
> assigned, the Container object is created which creates a container token
> that expires in roughly 10 minutes by default.
> This means that by the time the NM frees up enough space on that node for the
> container to move to assigned the container token may have expired.
