Craig Condit created YUNIKORN-2083:
--------------------------------------
Summary: Scheduler in standard mode should be able to handle pods
with no applicationID defined
Key: YUNIKORN-2083
URL: https://issues.apache.org/jira/browse/YUNIKORN-2083
Project: Apache YuniKorn
Issue Type: Improvement
Components: shim - kubernetes
Reporter: Craig Condit
Assignee: Craig Condit
The scheduler in plugin mode can handle the case where a Pod is defined with
schedulerName: yunikorn but no applicationID set can still be scheduled; it is
treated as a non-YuniKorn pod and passed through the default scheduler logic.
However, in the standard deployment mode we don't have any way to handle such
pods, as there is no default scheduler embedded. Currently, these pods simply
vanish and are never scheduled, leading to subtle problems and
difficult-to-diagnose issues.
It would be useful if these pods could be scheduled anyway, ideally using the
same algorithm for applicationID generation that the admission controller uses.
This would make standalone yunikorn more useful as a default scheduler
replacement.
