API-based configuration of Capacity Scheduler queue configuration
----------------------
The OrgQueue extension to the capacity scheduler provides a programmatic way to
change configurations by providing a REST API that users can call to modify
queue configurations. This enables automation of queue configuration management
by administrators in the queue's `administer_queue` ACL.
See [YARN-5734](https://issues.apache.org/jira/browse/YARN-5734) and the
[Capacity Scheduler documentation](./hadoop-yarn/hadoop-yarn-site/CapacityScheduler.html) for more information.
YARN Resource Types
---------------
The YARN resource model has been generalized to support user-defined countable resource types beyond CPU and memory. For instance, the cluster administrator could define resources like GPUs, software licenses, or locally-attached storage. YARN tasks can then be scheduled based on the availability of these resources.
See [YARN-3926](https://issues.apache.org/jira/browse/YARN-3926) and the [YARN resource model documentation](./hadoop-yarn/hadoop-yarn-site/ResourceModel.html) for more information.
