> Key: YUNIKORN-2789
> URL: https://issues.apache.org/jira/browse/YUNIKORN-2789
> Project: Apache YuniKorn
> Issue Type: Bug
> Components: core - common
> Reporter: Wilfred Spiegelenburg
> Assignee: Wilfred Spiegelenburg
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.6.0
>
>
> We have documented for queue resources that:
> {quote}Resources that are not specified in the list are not limited, for max
> resources, or guaranteed in the case of guaranteed resources.
> {quote}
> However in the implementation on the queue, internalGetMax, we call
> resources.ComponentWiseMin(). This returns 0 values for each type that is not
> defined in the two resources passed in. That does not line up.
> Example for getting the maximum resources of a queue using GetMaxQueueSet
> what I would expect based on the documentation:
>
> {code:java}
> parent: max{memory: 100G}
> parent.child: max{vcore: 100}
> => result child max{memory: 100G, vcore: 100}{code}
>
>
> currently we get:
> {code:java}
> parent: max{memory: 100G}
> parent.child: max{vcore: 100}
> => result child max{memory: 0, vcore: 0}{code}
> Similar when we add the root and call GetMaxResource:
> {code:java}
> root: max{memory: 100G, vcore: 200}
> root.parent: max{vcore: 100}
> root.parent.child: max{nvidia.com/gpu: 10}
> => result parent max{memory: 0, vcore: 100}
> => result child max{memory: 0, vcore: 0, nvidia.com/gpu: 0}{code}
> The fact that the resource type does not exist, even in the root, should not
> mean a zero set. The nodes that expose the specific resource might not have
> been registered or scaled up yet.
