Wilfred Spiegelenburg commented on YUNIKORN-2517:
-------------------------------------------------
We need to define how we want to behave and how we communicate back to the
submitter.
The approach taken in YUNIKORN-2933 is really harsh and does not take into
account differences in resources in duplicate task groups

> Key: YUNIKORN-2517
> URL: https://issues.apache.org/jira/browse/YUNIKORN-2517
> Project: Apache YuniKorn
> Issue Type: Bug
> Components: core - scheduler
> Reporter: Rajesh Kanhaiya Lal

> Hi Team , I am getting incorrect placeholder count for the duplicate task
> groups in gang scheduling.
> Example :
> {code:java}
> TaskGroups: []v1alpha1.TaskGroup{
> {Name: "groupdup", MinMember: int32(3),
> MinResource: map[string]resource.Quantity{
> "cpu": resource.MustParse("10m"),
> "memory": resource.MustParse("10M"),
> }},
> {Name: "groupdup", MinMember: int32(5),
> MinResource: map[string]resource.Quantity{
> "cpu": resource.MustParse("10m"),
> "memory": resource.MustParse("10M"),
> }},
> {Name: "groupa", MinMember: int32(7),
> MinResource: map[string]resource.Quantity{
> "cpu": resource.MustParse("10m"),
> "memory": resource.MustParse("10M"),
> }},
> }, {code}
> for the above config, we are getting a total of 17 pods ( 2 groups. + 15
> Placeholders).
> It's adding the duplicate group placeholder as well.
> Could you please take a look?
