----------------------------------
Summary: Topic creation allows invalid config values on running
brokers
Key: KAFKA-4987
URL: https://issues.apache.org/jira/browse/KAFKA-4987
Project: Kafka
Issue Type: Bug
Affects Versions: 0.10.2.0, 0.10.1.0
Reporter: dan norwood
we use kip4 capabilities to make a `CreateTopicsRequest` for our topics. one of
the configs we use is `cleanup.policy=compact, delete`. this was inadvertently
run against a cluster that does not support that policy. the result was that
the topic was created, however on subsequent broker bounce the broker fails to
start up

i believe that the broker should fail when given an invalid config during topic
creation
