Description

Hadoop clusters have the ability to restrict CPU usage for Samza applications by utilizing Control Groups, (Cgroups). Before enabling CPU enforcement on Hadoop clusters, application owners must have a way of knowing when their application is being throttled by Cgroups. This is to add a new Cgroup metric that makes application owners aware if their Samza container's CPU usage is being throttled by control groups.
