> [YARN-5764|https://issues.apache.org/jira/browse/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.
