Wilfred Spiegelenburg updated YUNIKORN-946:
-------------------------------------------
Description:
Even when executors are deleted, YK UI shows that resources are consumed by the
pod (the one which is already deleted). _kubectl get pods_ does not show the
executor but YK UI shows the information of a deleted pod consuming resources
even after few hours.
It results into leaking cluster resources.
Steps:
# Run a spark application using k8s spark operator
# Wait for executors to be in running state.
# Delete the application using `kubectl delete sparkapplications <appName>` OR
`kubectl delete {-}{{-}}f <yaml\{-}file>`
# All the driver and executor pods would be deleted. check `kubectl get pods`
# However, YK UI still shows some of the executors running and consuming
resources. It leads to leak of the resource as they are considered as used and
could not be used by pending pods.
