> Implement dynamic requests handling in CapacityScheduler
> --------------------------------------------------------
>
> Key: YARN-11781
> URL: https://issues.apache.org/jira/browse/YARN-11781
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: capacityscheduler
> Reporter: Tao Yang
> Assignee: Tao Yang
> Priority: Major
> Labels: pull-request-available
>
> This feature introduces a dynamic request handling mechanism in the
> CapacityScheduler, allowing for the modification of resource and scheduling
> requests based on configurable rules. This enables more flexible and adaptive
> resource management without requiring a restart of the ResourceManager.
> Benefits:
> * Increased Flexibility: Administrators can define custom rules for
> modifying requests, allowing for more tailored resource allocation strategies.
> * Enhanced Scheduling: The ability to convert ResourceRequest to
> SchedulingRequest opens up new possibilities for advanced scheduling and
> placement constraints.
