while performing some tests on our existing minikube and k8s infrastructure, i noticed that the integration tests were failing. i dug in and discovered the following message buried at the end of the stacktrace:
after i added the 'nss' package to resource-managers/kubernetes/docker/src/main/dockerfiles/spark/Dockerfile, everything worked.
i will also check and see if this is failing on 2.4...
tbh, i have no idea why this literally started failing today and not earlier. the only recent change to this file that i can find is https://issues.apache.org/jira/browse/SPARK-26995
