Attachment: bundling.docx
> Bundling: Searching for multiple containers in a single pass over {queues,
> applications, priorities}
> ----------------------------------------------------------------------------------------------------
>
> Key: YARN-4056
> URL: https://issues.apache.org/jira/browse/YARN-4056
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: capacityscheduler, resourcemanager, scheduler
> Reporter: Srikanth Kandula
> Attachments: bundling.docx
>
>
> 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}.
