Miklos Szegedi created YARN-5849: ------------------------------------ Summary: Automatically create YARN control group for pre-mounted cgroups Key: YARN-5849 URL: https://issues.apache.org/jira/browse/YARN-5849 Project: Hadoop YARN Issue Type: Improvement Affects Versions: 3.0.0-alpha1, 2.7.3, 3.0.0-alpha2 Reporter: Miklos Szegedi Assignee: Miklos Szegedi Priority: Minor
Yarn can be launched with linux-container-executor.cgroups.mount set to false. It will search for the cgroup mount paths set up by the administrator parsing the /etc/mtab file. You can also specify resource.percentage-physical-cpu-limit to limit the CPU resources assigned to containers. linux-container-executor.cgroups.hierarchy is the root of the settings of all YARN containers. If this is specified but not created YARN will fail at startup: Caused by: java.io.FileNotFoundException: /cgroups/cpu/hadoop-yarn/cpu.cfs_period_us (Permission denied) org.apache.hadoop.yarn.server.nodemanager.util.CgroupsLCEResourcesHandler.updateCgroup(CgroupsLCEResourcesHandler.java:263) This JIRA is about automatically creating YARN control group in the case above. It reduces the cost of administration. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
