Subject [jira] [Updated] (YARN-2440) Cgroups should limit YARN containers to cores allocated in yarn-site.xml
Date Fri, 22 Aug 2014 09:38:11 GMT

Varun Vasudev updated YARN-2440:
--------------------------------

    Attachment: screenshot-current-implementation.jpg

Screenshot with the CPU usage in the current implementation. In my yarn-site.xml, I had set
yarn.nodemanager.resource.cpu-vcores to 2. The python script is taking up as many cores as
it can.

The quota for the yarn group was set to -1.

varun@ubuntu:/var/hadoop/hadoop-3.0.0-SNAPSHOT$ cat /cgroup/cpu/yarn/cpu.cfs_quota_us
-1
