Subject [jira] [Created] (YARN-7715) Update CPU and Memory cgroups params on container update as well.

---------------------------------

             Summary: Update CPU and Memory cgroups params on container update as well.
                 Key: YARN-7715
                 URL: https://issues.apache.org/jira/browse/YARN-7715
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Arun Suresh


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.
