> 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
