Arun Suresh commented on YARN-6599:
-----------------------------------
Thanks for the update [~leftnoteasy]
I just have couple of minor comments:
As we discussed offline, to maintain consistency with the processor approach,
atleast at an API level, can we do the following: Currently, the processor
expects all placement constraints for the app to sent in the register call. Any
placement constraint specified in the SchedulingRequest should be an override
of the constraints specified in the mapping provided in the registerAM call.
The mapping that is sent in the register call is of the form {{Map<Set<String>,
PlaccementConstrint>}}, where the key is a set of allocation tags. Then in the
specific schedulingRequest, we refer to the PlacementConstraint using the
allocation tags (The PlacementConstraintsManager holds the mapping). This means
you need to set the allocation tags in the scheduling request. If the
SchedulingRequest contains a PlacementRequest, then it will first replace the
mapping in the PlacementConstraintsManager and then apply the constraints to
the SchedulingRequest.
Am +1 after that
