Carlo Curino commented on YARN-5871:
------------------------------------
This initial (rough) patch provides an idea of how we can:
1) extend the FederationStateStore APIs (with memory implementation)
2) extend the FederationRouterPolicy APIs
3) implement (for all current Router policies) the handling of reservations
4) tests
This is probably worth splitting down to multiple patches, but I am uploading
to start the discussion.
The current design covers the support for reservations *in a single
sub-cluster*. Spanning reservations across sub-cluster is rather complex, and
should come later (likely require an umbrella JIRA on its own).
> Add support for reservation-based routing.
