Comment 5 ge liu 2020-03-02 11:15:45 UTC

Checked latest build log this issue still exist(https://storage.googleapis.com/origin-ci-test/pr-logs/pull/openshift_cluster-network-operator/456/pull-ci-openshift-cluster-network-operator-master-e2e-gcp/792/artifacts/e2e-gcp/pods/openshift-etcd-operator_etcd-operator-67999b8f7b-zvswh_operator.log),
but think about the fix have been merged at Feb 25, and latest build log is Feb 21, so the code should have been merged now, and close it because the clone bug add no-qe tag.
