> Key: YARN-9652
> URL: https://issues.apache.org/jira/browse/YARN-9652
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: reservation system, scheduler
> Affects Versions: 3.3.0
> Reporter: Erkin Alp Güney
> Priority: Major
>
> 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.
