[jira] [Commented] (YARN-7403) [GQ] Compute global and local "IdealAllocation"

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. > [GQ] Compute global and local "IdealAllocation" > --- > > Key: YARN-7403 > URL: https://issues.apache.org/jira/browse/YARN-7403 > 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, > YARN-7403.draft3.patch, YARN-7403.v1.patch, YARN-7403.v2.patch, > global-queues-preemption.PNG > > > 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.

I would suggest to split it in two parts to make it easier to follow. The first can be the data structures to model the federated cluster and the second the algos for rebalancing.

Carlo Curino commented on YARN-7403:
The v1 patch contains a much reworked version of the code. This depends on
YARN-7934 so will not compile. The key idea here is to provide algorithms that
will run every few seconds in the GPG and observe the overall state of a
federated cluster. The algorithm will leverage some of the
{{PreemptableResourceCalculator}} logic (with several additions) to compute
what is the ideal allocation for each queues. The extra effort is put into
considering "locality" among sub-clusters, which require some careful
consideration. Various heuristics can be chosen from (we implement two as
reference), and once YARN-7885/YARN-7886 will be ready to use we can experiment
on which is most closely approximating the behavior of a single
{{CapacityScheduler}} overlooking the entire federation.

> This JIRA tracks algorithmic effort to combine the local queue views of
> capacity guarantee/use/demand and compute the global amount of preemption,
> and based on that, "where" (in which sub-cluster) preemption will be enacted.
