--------------------------------
Summary: Use cgroup to get container resource utilization
Key: YARN-6668
URL: https://issues.apache.org/jira/browse/YARN-6668
Project: Hadoop YARN
Issue Type: Improvement
Components: nodemanager
Affects Versions: 3.0.0-alpha3
Reporter: Haibo Chen
Assignee: Haibo Chen
Container Monitor relies on proc file system to get container resource
utilization, which is not as efficient as reading cgroup accounting. We should
in NM, when cgroup is enabled, read cgroup stats instead.
