Boyang Chen updated KAFKA-12381:
--------------------------------
Component/s: core
> Incompatible change in verifiable_producer.log in 2.8
> -----------------------------------------------------
>
> Key: KAFKA-12381
> URL: https://issues.apache.org/jira/browse/KAFKA-12381
> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 2.8.0
> Reporter: Colin McCabe
> Assignee: Boyang Chen
> Priority: Blocker
>
> In test_verifiable_producer.py , we used to see this error message in
> verifiable_producer.log when a topic couldn't be created:
> WARN [Producer clientId=producer-1] Error while fetching metadata with
> correlation id 1 : {test_topic=LEADER_NOT_AVAILABLE}
> (org.apache.kafka.clients.NetworkClient)
> The test does a grep LEADER_NOT_AVAILABLE on the log in this case, and it
> used to pass.
> Now we are instead seeing this in the log file:
> WARN [Producer clientId=producer-1] Error while fetching metadata with
> correlation id 1 : {test_topic=INVALID_REPLICATION_FACTOR}
> (org.apache.kafka.clients.NetworkClient)
> And of course now the test fails.
> The INVALID_REPLICATION_FACTOR is coming from the new auto topic creation
> manager.
> It is a simple matter to make the test pass -- I have confirmed that it
> passes if we grep for INVALID_REPLICATION_FACTOR in the log file instead of
> LEADER_NOT_AVAILABLE.
> I think we just need to decide if this change in behavior is acceptable or
> not.
