Benjamin Teke created YARN-11743: ------------------------------------ Summary: Cgroup v2 support should fall back to v1 when there are no v2 controllers Key: YARN-11743 URL: https://issues.apache.org/jira/browse/YARN-11743 Project: Hadoop YARN Issue Type: Sub-task Components: yarn Reporter: Benjamin Teke
Cgroup v1/v2 mixed mode support was introduced in YARN-11692, however it does not support an edgecase where NM has the cgroup v2 support enabled (using {{yarn.nodemanager.linux-container-executor.cgroups.v2.enabled}} set to true), but there are only cgroup v1 controllers mounted. In larger clusters there is a chance that some part of the cluster is already on newer OSes with cgroup v2 as a default, and others are still using v1. Currently trying to launch an NM with cgroup v2 support enabled will fail if there are no cgroup.controllers file present. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
