> Cleanup FixedValueResource to avoid dependency to ResourceUtils

> Key: YARN-7410
> URL: https://issues.apache.org/jira/browse/YARN-7410
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 3.1.0
> Reporter: Sunil G
> Assignee: Wangda Tan
> Priority: Major

> After YARN-7307, Client/AM don't need to keep a up-to-dated resource-type.xml
> in the classpath. Instead, they can use YarnClient/ApplicationMasterProtocol
> APIs to get the resource types from RM and refresh local types.
> One biggest issue of this approach is FixedValueResource: Since we initialize
> FixedValueResource in static block, and they won't be updated if resource
> types refreshed.
> So we need to properly update FixedValueResource to make it can get
> up-to-date results
