Description sdasu 2021-11-08 20:35:27 UTC 
The "oc explain" tests fail pretty frequently where each time it fails for a different resource.
For example:
In https://prow.ci.openshift.org/view/gs/origin-ci-test/logs/periodic-ci-openshift-release-master-nightly-4.8-e2e-metal-ipi-ovn-ipv6/1449206905837719552, it is:
failed to explain ["clusterroles.rules" "--api-version=authorization.openshift.io/v1"]
In https://prow.ci.openshift.org/view/gs/origin-ci-test/logs/periodic-ci-openshift-release-master-nightly-4.8-e2e-metal-ipi-ovn-ipv6/1449992496774909952, it is:
failed to explain ["deploymentconfigs.status.replicas" "--api-version=apps.openshift.io/v1"]
In https://prow.ci.openshift.org/view/gs/origin-ci-test/logs/periodic-ci-openshift-release-master-nightly-4.8-e2e-metal-ipi-ovn-ipv6/1453388863056646144, it is:
failed to explain ["installplans" "--api-version=operators.coreos.com/v1alpha1"]
and so on.

And we see similar msgs in the logs:
[AfterEach] [sig-cli] oc explain
  github.com/openshift/origin/test/extended/util/client.go:141
STEP: Destroying namespace "e2e-test-oc-explain-hx9f4" for this suite.
fail [github.com/openshift/origin/test/extended/cli/explain.go:450]: Unexpected error:
    <*errors.errorString | 0xc002e7c7a0>: {
        s: "failed to explain [\"installplans\" \"--api-version=operators.coreos.com/v1alpha1\"]: exit status 1",
    }
    failed to explain ["installplans" "--api-version=operators.coreos.com/v1alpha1"]: exit status 1
occurred

Indicating that the Namespace required to run the test is deleted before the test has finished executing.
Comment 1 sdasu 2021-12-17 16:33:04 UTC 
As a result of the fix added for https://bugzilla.redhat.com/show_bug.cgi?id=2018208, these tests are no longer failing frequently. So, at this point it is dafe to close this BZ and the attached PR.
