> Key: YUNIKORN-1091
> URL: https://issues.apache.org/jira/browse/YUNIKORN-1091
> Project: Apache YuniKorn
> Issue Type: Bug
> Components: shim - kubernetes
> Reporter: Wilfred Spiegelenburg
> Assignee: Manikandan R
> Priority: Critical
>
> {{ctx.updateNode()}} gets called by the K8s client event handling. This updates the two caches using two calls:
> # {{ctx.schedulerCache.UpdateNode()}}
> # {{ctx.nodes.updateNode()}}
> The first call adds the node (type _framework.NodeInfo_) if it does not exist and otherwise replaces the entry in the cache with the new info (GOOD)
> The second call adds the node (type _SchedulerNode_) if it does no exist to (GOOD). If the node exists it checks for a resource change. The call results in a notification of the scheduler core. It does NOT update the secondary cache with this change. This leaves the SchedulerNode capacity unchanged and out of sync.
