Summary: SimplePreemptor e2e test doesn’t really wait for pod’s
Killing event
Key: YUNIKORN-2043
URL: https://issues.apache.org/jira/browse/YUNIKORN-2043
Project: Apache YuniKorn
Issue Type: Bug
Components: test - e2e
Reporter: Yu-Lin Chen
Assignee: Yu-Lin Chen
In the e2e simple_preemptor_test, the current timeout for ‘waiting Killing
event’ is in nanosecond.
# 120 ns:
[test/e2e/simple_preemptor/simple_preemptor_test.go#L169|https://github.com/apache/yunikorn-k8shim/blob/master/test/e2e/simple_preemptor/simple_preemptor_test.go#L169]
# 1200 ns:
[test/e2e/simple_preemptor/simple_preemptor_test.go#L215|https://github.com/apache/yunikorn-k8shim/blob/master/test/e2e/simple_preemptor/simple_preemptor_test.go#L215]
The interval is
Millisecond*100([code|https://github.com/apache/yunikorn-k8shim/blob/master/test/e2e/framework/helpers/k8s/k8s_utils.go#L725]).
So there is no actual 'waiting' happening here.
This issue will trigger an error in the CI even though the pod has been killed.
(Note: Not all SimplePreemptor fails are caused by this issue, there are still
other unkown issues to be investigated.)
