Anubhav Dhoot reassigned YARN-3119: ----------------------------------- Assignee: Anubhav Dhoot > Memory limit check need not be enforced unless aggregate usage of all > containers is near limit > ---------------------------------------------------------------------------------------------- > > Key: YARN-3119 > URL: https://issues.apache.org/jira/browse/YARN-3119 > Project: Hadoop YARN > Issue Type: Improvement > Components: nodemanager > Reporter: Anubhav Dhoot > Assignee: Anubhav Dhoot > Attachments: YARN-3119.prelim.patch > > > Today we kill any container preemptively even if the total usage of > containers for that is well within the limit for YARN. Instead if we enforce > memory limit only if the total limit of all containers is close to some > configurable ratio of overall memory assigned to containers, we can allow for > flexibility in container memory usage without adverse effects. This is > similar in principle to how cgroups uses soft_limit_in_bytes. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
