Mate Czagany commented on FLINK-31717:
--------------------------------------
Sorry, I didn't have much time to work on this ticket so far.
I've investigated and found 3 test cases that load ~/.kube/config in some ways:
* FlinkOperatorTest
* FlinkOperatorITCase
* HealthProbeTest
I could add jenvtest to FlinkOperatorTest easily. I had to re-write some of the
code in HealthProbeTest.java so it doesn't try to call FlinkOperator.run() to
start OperatorHealthService.
But I could not get around FlinkOperatorITCase since that test class is about
testing a Kubernetes cluster that already has the operator installed.
What do you suggest we do with that test case?
