Attachment: YARN-5764-v1.patch
> NUMA awareness support for launching containers
> -----------------------------------------------
>
> Key: YARN-5764
> URL: https://issues.apache.org/jira/browse/YARN-5764
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: nodemanager, yarn
> Reporter: Olasoji
> Assignee: Devaraj K
> Attachments: NUMA Awareness for YARN Containers.pdf,
> YARN-5764-v0.patch, YARN-5764-v1.patch
>
>
> The purpose of this feature is to improve Hadoop performance by minimizing
> costly remote memory accesses on non SMP systems. Yarn containers, on launch,
> will be pinned to a specific NUMA node and all subsequent memory allocations
> will be served by the same node, reducing remote memory accesses. The current
> default behavior is to spread memory across all NUMA nodes.
