[jira] [Comment Edited] (YUNIKORN-1159) Node occupied resources are not detected on YuniKorn startup
[ https://issues.apache.org/jira/browse/YUNIKORN-1159?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17514272#comment-17514272 ]

We may need a follow-up for this one. It has been pointed out that this code: [https://github.com/apache/yunikorn-k8shim/blob/76ddb316bd099fc783a698d3a8fb3d5543cdaf21/pkg/cache/context_recovery.go#L96...L128] should account for the occupied resources during recovery. We need to determine why that is no longer the case.

> Key: YUNIKORN-1159
> URL: https://issues.apache.org/jira/browse/YUNIKORN-1159
> Project: Apache YuniKorn
> Issue Type: Bug
> Components: shim - kubernetes
> Reporter: Craig Condit
> Assignee: Craig Condit
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.0.0
>
>
> When YuniKorn starts up on a Kubernetes cluster, the occupied resources of existing nodes are not properly detected. This can lead to YuniKorn over-allocating resources on a node and resulting in a failure of pods to schedule.
> Restarting a pod on a node will cause the occupied values of the node to refresh properly.
