Gabor Somogyi commented on SPARK-30541:
---------------------------------------
As I see there are 2 problems:
* Kafka broker is not coming up in time: I've had discussion with the Kafka
guys and their solution to this is to execute their test with retry
* Client not found in Kerberos database: which is reproduced here:
[https://github.com/apache/spark/pull/27810]
I'm going to attach the logs for the second problem here not because jenkins
results going to disappear.
