Devaraj K updated YARN-5764:
----------------------------
Fix Version/s: (was: 2.6.0)
> 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
> Affects Versions: 2.6.0
> Environment: SW: CentOS 6.7, Hadoop 2.6.0
> Processors: Intel Xeon CPU E5-2699 v4 @2.20GHz
> Memory: 256GB 4 NUMA nodes
> Reporter: Olasoji
>
> 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.
