I'd like to propose including integration testing for Kerberos on the Spark 2.4 release: https://github.com/apache/spark/pull/22608
Arguments in favor: 1) it improves testing coverage on a feature important for integrating with HDFS deployments 2) its intersection with existing code is small - it consists primarily of new testing code, with a bit of refactoring into 'main' and 'test' sub-trees. These new tests appear stable. 3) Spark 2.4 is still in RC, with outstanding correctness issues. The argument 'against' that I'm aware of would be the relatively large size of the PR. I believe this is considered above, but am soliciting community feedback before committing. Cheers, Erik
