Varun Vasudev updated YARN-2440: -------------------------------- Attachment: apache-yarn-2440.2.patch Uploaded a new patch. It adds two new parameters to the YARN configuration. 1. yarn.nodemanager.containers-cpu-cores - can be set to the number of cores admins want YARN containers to use. 2. yarn.nodemanager.containers-cpu-percentage - can be set a percentage of overall CPU that admins want YARN containers to use. By default, we use all cores. I've also updated the description of yarn.nodemanager.resource.cpu-vcores to what I think is a more accurate version. > Cgroups should allow YARN containers to be limited to allocated cores > --------------------------------------------------------------------- > > Key: YARN-2440 > URL: https://issues.apache.org/jira/browse/YARN-2440 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Varun Vasudev > Assignee: Varun Vasudev > Attachments: apache-yarn-2440.0.patch, apache-yarn-2440.1.patch, > apache-yarn-2440.2.patch, screenshot-current-implementation.jpg > > > The current cgroups implementation does not limit YARN containers to the > cores allocated in yarn-site.xml. -- This message was sent by Atlassian JIRA (v6.2#6252)
