----------------------------------------
Is this similar to {{assignMultiple}} in {{FairScheduler}}?
> Bundling: Searching for multiple containers in a single pass over {queues,

> More than one container is allocated on many NM heartbeats. Yet, the current
> scheduler allocates exactly one container per iteration over {{queues,
> applications, priorities}}. When there are many queues, applications, or
> priorities allocating only one container per iteration can needlessly
> increase the duration of the NM heartbeat.
>
> In this JIRA, we propose bundling. That is, allow arbitrarily many containers
> to be allocated in a single iteration over {{queues, applications and
> priorities}}.
