> Address performance issue when 3+ resource types configured in the system

> Key: YARN-7158
> URL: https://issues.apache.org/jira/browse/YARN-7158
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager, resourcemanager
> Reporter: Wangda Tan
> Assignee: Wangda Tan
> Priority: Critical
>
> In existing YARN-3926 branch, we use BaseResource to handle 2 mandatory
> resource types (memory+cpu) configured in the system. Once we have 3 or more
> resource types configured in the system. YARN will use ResourcePBImpl to
> initialize resource objects, which will be very expensive. We should update
> BaseResource when do resource calculation in RM instead of using PB-backed
> resource implementation.
