> 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.
