URL: https://github.com/apache/kafka/pull/8081
 
 
   Relying on integration test to catch an algorithm bug introduces more flakiness, reduce the test into a unit test to reduce the flakiness until we upgrade Java/Scala libs.

> KAFKA-9335 introduces an integration test to verify the topology builder itself could survive from building a complex topology. This test gets flaky some time for stream client to broker connection, so we should consider making it less flaky by either converting to a unit test or just focus on making the test logic more robust.
