--------------------------------
Hi, [~cheersyang], could you please help to give contributor permission to
[~zyb] and review this issue?
Findbugs warnings are unrelated to this patch(will be resolved in YARN-9495).
Regarding the test case, there is no existing case to test fields in
ApplicationResourceUsageReport, this bug is obvious and the fix is clean
enough, I think it's fine for the patch without a test case.

> when getting an ApplicationResourceUsageReport instance from the class of
> SchedulerApplicationAttempt, I found the input constructor
> parameter(reservedContainers.size()) is wrong. because the type of this
> variable is Map<SchedulerRequestKey, Map<NodeId, RMContainer>>, so
> "reservedContainer.size()" is not the number of containers, but the number of
> SchedulerRequestKey.
