Stavros Kontopoulos commented on SPARK-26997:
---------------------------------------------
[~vanzin] I run the tests successfully with the latest minikube version
(v0.34.1) and k8s 1.13.3. It is a compatibility issue AFAIK. I have seen the
failures in our intern ci as well.
[~shaneknapp] one problem though is that while in theory using something like `
--kubernetes-version=v1.11.7` should work for targeting any k8s version it
didnt. It failed with: `Caused by: java.net.UnknownHostException:
kubernetes.default.svc: Try again to make tests pass for
https://github.com/apache/spark/pull/23514.
> k8s integration tests failing after client upgraded to 4.1.2

> Not sure if this is a client bug or a compatibility issue.
