Carlo Curino commented on YARN-7403:
------------------------------------
[~kkaranasos] thanks for looking at this. I initially put it together because
it is not easy to understand why we have certain data structures without the
code that use them, but if it is easier to review for you I am ok to split.
# YARN-7953 is now a data-structure only patch (with minor refactoring should
now compile fine, and be reasonably self-sustaining)
# YARN-7403 (this patch) is now algo-only and depends on YARN-7953 and
YARN-7934 (the hook in CS/preemption code patch)
BTW the choice of JAX-B is because we are considering REST endpoint as a way to
communicate between RM and GPG.

> 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).
