Description

YARN-5764 has added NUMA Awareness support for launching containers. This improves the workload performance on machines which has NUMA support like EC2 m5.24x.

Currently this feature works only on LinuxContainerExecutor and not on DefaultContainerExecutor. Have seen users configuring on a DefaultContainerExecutor by mistake and has not found any improvement. Suggest to document how to enable NUMA in YARN.
