      Description

      YARN-3 introduced CPU isolation and monitoring through cgroups. YARN-2 and introduced CPU scheduling in the capacity scheduler, and YARN-326 will introduce it in the fair scheduler. The number of virtual cores allocated to a container should be used to weight the number of cgroups CPU shares given to it.
