Ryan Lo commented on YUNIKORN-2406:
-----------------------------------
I also tested the latest version, and my testing steps are following:
1. deploy nginx app
{code:java}
kubectl apply -f yunikorn-k8shim/deployments/examples/nginx/nginx.yaml{code}
2. try container history endpoint (/ws/v1/history/containers)
{code:java}
[
{
"timestamp": 1707824440925032294,
"totalContainers": "1"
}
] {code}
3. restart the scheduler
{code:java}
kubectl rollout restart deploy/yunikorn-scheduler{code}
4. try /ws/v1/history/containers again, see the "totalContainers" is zero but
nginx app is running
{code:java}
[
{
"timestamp": 1707824260926341294,
"totalContainers": "0"
},
{
"timestamp": 1707824320926063169,
"totalContainers": "0"
},
{
"timestamp": 1707824380925316419,
"totalContainers": "0"
}
]{code}
5. try /ws/v1/metrics, see the count of containers is correct
{code:java}
yunikorn_root_default_queue_container{state="allocated"} 1 {code}
> the count of allocated containers is not updated in adding recovered
> allocation

> Key: YUNIKORN-2406
> URL: https://issues.apache.org/jira/browse/YUNIKORN-2406
> Project: Apache YuniKorn
> Issue Type: Bug
> Components: core - scheduler
> Reporter: Chia-Ping Tsai
> Priority: Major
>
> The following events will update the count of allocated containers.
> 1. release allocation
> 2. schedule new allocation
> 3. remove a node
> Unfortunately, the event of recovering allocations does not update the count.
> Hence, the restarted scheduler shows zero value of allocated containers even
> though there are a bunch of running containers.
> This bug cause the restful API of showing container history will return zero,
> and so the dashboard of WEB UI shows zero also.
