Summary: Doc on how to configure NUMA in YARN
Key: YARN-11195
URL: https://issues.apache.org/jira/browse/YARN-11195
Project: Hadoop YARN
Issue Type: Improvement
Components: documentation
Affects Versions: 3.3.3
Reporter: Prabhu Joseph
Assignee: Prabhu Joseph
[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.
