> Yunikorn plugin inconsistent node assignment + scheduling
> ---------------------------------------------------------
>
> Key: YUNIKORN-1165
> URL: https://issues.apache.org/jira/browse/YUNIKORN-1165
> Project: Apache YuniKorn
> Issue Type: Bug
> Components: shim - kubernetes
> Reporter: Ronald Zhang
> Assignee: Craig Condit
> Priority: Major
> Labels: pull-request-available
>
> Although the plugin selects a certain node, the default scheduler may not
> schedule the pod on the plugin-selected node. In the below example, Yunikorn
> selected node host-05.shared-ek8s-dev-01.kcloud.cloudera.com. However, the
> pod was scheduled on host-01.shared-ek8s-dev-01.kcloud.cloudera.com.
> Internally, Yunikorn still incorrectly believes that the node was scheduled
> on host-05.shared-ek8s-dev-01.kcloud.cloudera.com.
