             Summary: Convert QueueManager from a protocol-only type to a basic hierarchical queue implementation
                 Key: YARN-9652
                 URL: https://issues.apache.org/jira/browse/YARN-9652
             Project: Hadoop YARN
          Issue Type: New Feature
          Components: reservation system, scheduler
    Affects Versions: 3.3.0
            Reporter: Erkin Alp Güney


SchedulerQueueManager is currently an interface aka a protocol-only type. As seen in the codebase, each scheduler implements the queue configuration and management stuff over and over. If we convert it into a base concrete class with simple implementation of hierarchical queue system (as in Fair and Capacity schedulers), pluggable schedulers may be developed more easily.
