Haibo Chen created YARN-8930: -------------------------------- Summary: CGroup-based strict container memory management does not work with CGroupElasticMemoryController Key: YARN-8930 URL: https://issues.apache.org/jira/browse/YARN-8930 Project: Hadoop YARN Issue Type: Bug Components: nodemanager Affects Versions: 3.2.0 Reporter: Haibo Chen Assignee: Haibo Chen
When yarn.nodemanger.resource.memory.enforced is set to true with memory cgroup turned on, (aka strict memory enforcement), containers monitor relies on the under_oom status read from the container cgroup's memory.oom_control file. However, when the root yarn container cgroup is under oom (e.g. when the node is overallocating iteself), the under_oom status is set for all yarn containers regardless of whether each individual container has run over its memory limit. What essentially happens is that whenever the root cgroup is under oom, all yarn containers are killed. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
