[jira] [Created] (YARN-8461) Support strict memory control on
individual container with elastic control memory mechanism
Haibo Chen created YARN-8461:
--------------------------------
Summary: Support strict memory control on individual container with elastic control memory mechanism
Key: YARN-8461
URL: https://issues.apache.org/jira/browse/YARN-8461
Project: Hadoop YARN
Issue Type: Improvement
Components: nodemanager
Affects Versions: 3.2.0
Reporter: Haibo Chen
Assignee: Haibo Chen
YARN-4599 adds elastic memory control that disables oom killer for the root container cgroup. Hence, all containers have their oom killer disabled because they inherit the setting from the root container cgroup. Hence, when strict memory control on individual containers is also enabled, the container will be frozen but not killed. We can let the container monitoring thread to take care of the frozen containers.
