-----------------------------------------------
Summary: plugin mode: remove status update completely
Key: YUNIKORN-1562
URL: https://issues.apache.org/jira/browse/YUNIKORN-1562
Project: Apache YuniKorn
Issue Type: Bug
Components: shim - kubernetes
Reporter: Wilfred Spiegelenburg
Assignee: Wilfred Spiegelenburg
The k8shim in plugin mode only updates the pod status to move the pod from the
_unschedulablePods_ structure to the activeQ. This caused an issue in the way
we did it before YUNIKORN-1547 as we could leave a pod in a custom state that
K8s does not know.
After YUNIKORN-1547 we used the pending state. There could still be cases that
the state set by the plugin showed up and not the state that the pod was really
in. A pod could be fully scheduled and running while still showing pending as
set by the plugin.
The state change was added to the plugin code based on an incorrect assumption
that it would trigger a move between the _unschedulablePods_ and {_}activeQ{_}.
However the scheduler explicitly excluded pod status when checking for updates.
We should thus not set the status of the pod to limit side effects and impact.
