--------------------------------
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.
