---------------------------------
Thanks [~miklos.szeg...@cloudera.com] for review and commit, [~leftnoteasy] and
others for reviews.
[~miklos.szeg...@cloudera.com], is there any reason to keep this as still
'Unresolved'?

> 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.
