--------------------------------------------
Summary: Auto topic creation causes failure with older clusters
Key: KAFKA-5704
URL: https://issues.apache.org/jira/browse/KAFKA-5704
Project: Kafka
Issue Type: Bug
Components: KafkaConnect
Affects Versions: 0.11.0.0
Reporter: Ewen Cheslack-Postava
The new automatic internal topic creation always tries to check the topic and
create it if missing. However, older brokers that we should still be compatible
with don't support some requests that are used. This results in an
UnsupportedVersionException which some of the TopicAdmin code notes that it can
throw but then isn't caught in the initializers, causing the entire process to
fail.
We should probably just catch it, log a message, and allow things to proceed
hoping that the user has already created the topics correctly (as we used to
do).
