Inigo Goiri created YARN-3481:
---------------------------------
Summary: Report NM aggregated container resource utilization in
heartbeat
Key: YARN-3481
URL: https://issues.apache.org/jira/browse/YARN-3481
Project: Hadoop YARN
Issue Type: Improvement
Components: nodemanager, resourcemanager
Affects Versions: 2.7.0
Reporter: Inigo Goiri
Priority: Minor
To allow the RM take better scheduling decisions, it should be aware of the
actual utilization of the containers. The NM would aggregate the
ContainerMetrics and report it in every heartbeat.
Related to YARN-1012 but aggregated to reduce the heartbeat overhead.
