Issue 1:
The UT RemoteTaskRunnerTest.testRunPendingTaskFailToAssignTask failed in this build:

[ERROR] Tests run: 29, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 72.402 s <<< FAILURE! - in org.apache.druid.indexing.overlord.RemoteTaskRunnerTest

It is evidently known that this test is flaky:

// higher timeout to reduce flakiness on CI pipeline

The same test passes when run on a Mac in the IDE. The test passed in earlier builds on Travis in this branch. The branch in question changed only SQL classes, but nothing in the Overlord. Conclusion: flaky test.

Issue 2:
I used the unified console to create a Kafka Indexing supervisor and have been adding custom configurations in the consumer properties that include the bootstrap servers and a custom deserializer, which has worked flawlessly until I added another property (auto.offset.reset). When I look at the resulting log files, I see that the auto.offset.reset property is, in fact in my ingestSpec, but is not passed on to the Kafka consumer properties. My setting is 'earliest' and the consumer properties shows 'none'.

I have inspected org.apache.druid.indexing.kafka.KafkaConsumerConfigs and found that the probably culprit is that 'auto.offset.reset' is hard-coded. Perhaps the simplest fix might be to remove the hard-coded setting here, but maybe I am missing something:
