Labels: newbie (was: )
> Robust handling of invalid Task Group annotation
> ------------------------------------------------
>
> Key: YUNIKORN-1076
> URL: https://issues.apache.org/jira/browse/YUNIKORN-1076
> Project: Apache YuniKorn
> Issue Type: Bug
> Components: shim - kubernetes
> Reporter: Si Latt
> Priority: Major
> Labels: newbie
>
> For gang scheduling, task group information has to be defined in the
> annotation section. If the provided YAML for task group info is invalid, such
> as missing double quote for keys, it results in parse exception and gets
> logged in YK log. However, when looking at Kubernetes event log, there is no
> indication that exception happened during gang scheduling. Other gang
> scheduling events are logged and hence give users the wrong impression that
> pods are gang scheduled without any issue.
> Current behavior is dangerous as it cause gang scheduling to not work in
> production without users realizing any issue. We should probably take the
> following actions:
> # Reject / fail any app with invalid task group annotation
> # Emit exceptions in kubernetes events for surfacing critical events
> happening in the cluster.
