Miklos Szegedi commented on YARN-6384: -------------------------------------- [~lolee_k], CGROUP_CPU_PERIOD_US should never be set in non-strict mode. In strict mode, you could restrict to more than the vcores defaulting to 100%. > Add configuratin to set max cpu usage when strict-resource-usage is false > with cgroups > -------------------------------------------------------------------------------------- > > Key: YARN-6384 > URL: https://issues.apache.org/jira/browse/YARN-6384 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: dengkai > Attachments: YARN-6384-0.patch, YARN-6384-1.patch, YARN-6384-2.patch > > > When using cgroups on yarn, if > yarn.nodemanager.linux-container-executor.cgroups.strict-resource-usage is > false, user may get very more cpu time than expected based on the vcores. > There should be a upper limit even resource-usage is not strict, just like a > percentage which user can get more than promised by vcores. I think it's > important in a shared cluster. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
