Should we set it to 3 instead? IIRC, we run all system tests with 3 brokers? Wondering why the change broke the system tests, as they should have overwritten the default to 3 anyway?

Sounds like we don't override the default after all? Or we have at least one test where that slipped through 🤷♀️

I guess the logic scattered between Python and Java code... And maybe we need 3 only for EOS tests? Not sure either.
Also ok with me to just merge this PR as-is? Or should we update Java code instead?

Ah, yeah, I bet that's it: we only set it for the EOS tests. Might be better to just set it in the Java code instead as it's easier to find and read, and I believe most other configs are set there. I think this test runs the StreamsSmokeTest?

not really. streams_broker_compatibility_test.py run test with single broker ( https://github.com/apache/kafka/blob/trunk/tests/kafkatest/tests/streams/streams_broker_compatibility_test.py#L45)

I prefer to change python code rather than java code since the number of brokers is connected to replication refactor. If we add hardcode (i.e replication refactor = 1) in the java class, it is hard to change both of them in python.

Fine with me either way. Thanks for the fix
