------------------------------------
Fixing TestYarnConfigurationFields unit test failure (the rest still does not
compile as depends on YARN-7403).
> [GQ] Compute global and local "IdealAllocation"

> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: federation
> Reporter: Carlo Curino
> Assignee: Carlo Curino
> Priority: Major
> Attachments: YARN-7403.draft.patch, YARN-7403.draft2.patch,

> This JIRA tracks algorithmic effort to combine the local queue views of
> capacity guarantee/use/demand and compute the global ideal allocation, and
> the respective local allocations. This will inform the RMs in each
> sub-clusters on how to allocate more containers to each queues (allowing for
> temporary over/under allocations that are locally excessive, but globally
> correct).
