> In YARN-6673 and YARN-6674, the cgroups resource handlers update the cgroups params for the containers, based on opportunistic or guaranteed, in the *preStart* method.
> Now that YARN-5085 is in, Container executionType (as well as the cpu, memory and any other resources) can be updated after the container has started. This means we need the ability to change cgroups params after container start.
