>             Project: Apache YuniKorn
>          Issue Type: Bug
>          Components: core - scheduler

>            Priority: Major

> There is some recent change that caused the application resource usage report 
> to have a new format:
> Prior the change, the format was:
> {code:java}
> YK_APP_SUMMARY: {"appID": "adf53ee0-experiment-organicad-94520240-1-1", 
> "submissionTime": 1712169262131, "startTime": 1712169264134, "finishTime": 
> 1712173619983, "user": 
> "system:serviceaccount:spark-operator-02:spark-operator", "queue": 
> "root.queue-large", "state": "Completed", "rmID": "test-cluster", 
> "resourceUsage": 
> {"abc":{"memory":139178200478515200,"pods":1729129,"vcore":5183062000},"def":{"memory":113789789798400,"pods":1413,"vcore":4239000}},
>  "preemptedResource": {}}
>   {code}
> with the change, the new format is:
> {code:java}
>  2024-04-04T00:33:08.532Z     INFO    core.scheduler.application.usage        
> objects/application_summary.go:60       YK_APP_SUMMARY: {ApplicationID: 
> afa303d0-test-trino-sparksql--20240404-2-1, SubmissionTime: 1712190615461, 
> StartTime: 1712190617496, FinishTime: 1712190788532, User: 
> system:serviceaccount:spark-operator-01:spark-operator, Queue: 
> root.queue-large, State: Completed, RmID: test-cluster, ResourceUsage: 
> TrackedResource{UNKNOWN:pods=177,UNKNOWN:vcore=354000,UNKNOWN:memory=1431454089216},
>  PreemptedResource: TrackedResource{}, PlaceholderResource: 
> TrackedResource{}}{code}
> There are several incompatibilities:
> 1. the class name TrackedResource was not there before, now it is.
> 2. the instance type was outside the resource part before, not it's embedded
> 3. the instance type was reported correctly before the change, now it's 
> UNKNOWN
> #3 may be a different issue, but it's observed by us at the same time.
> I think what should change the format back to the original one, as this is an 
> incompatible change. What do you think [~wilfreds] , [~pbacsko] ,[~ccondit] ?
> Thanks.
