Ompal Singh updated YUNIKORN-3332:
----------------------------------
Component/s: shim - kubernetes
(was: core - common)
> Prevent timed out Placeholder creation
> --------------------------------------
>
> Key: YUNIKORN-3332
> URL: https://issues.apache.org/jira/browse/YUNIKORN-3332
> Project: Apache YuniKorn
> Issue Type: Task
> Components: shim - kubernetes
> Reporter: Ompal Singh
> Assignee: Ompal Singh
> Priority: Major
> Labels: newbie, pull-request-available
>
> On restart we should not create placeholders that are already timed-out. In
> certain restart scenarios we could be creating a placeholder that is already
> timed out.
> * Stop YuniKorn
> * Create a pod with gang definition and a short placeholder timeout
> * Start YuniKorn
> If the time between the pod creation and the start of YuniKorn is longer than
> the timeout the placeholders will immediately timeout on allocation.
> We have two choices:
> * not create the placeholders and directly push the real pod
> * set the time out based on the restart time of YuniKorn
> We must only do that for newly created placeholders not for existing ones.
