> 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.
