[jira] [Created] (YARN-10907) Investigate: Minimize usages of AbstractCSQueue#csContext

Szilard Nemeth created YARN-10907:
-------------------------------------

             Summary: Investigate: Minimize usages of AbstractCSQueue#csContext
                 Key: YARN-10907
                 URL: https://issues.apache.org/jira/browse/YARN-10907
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Szilard Nemeth


Context objects can be a sign of a code smell as they can contain many, possible loosely related references to other objects.
CapacitySchedulerContext seems like this.
This task is to investigate how the field AbstractCSQueue#csContext is being used from this class and possibly keeping the usage of this context class on the bare minimum.
