---------------------------------------------

             Summary: Topic message.max.bytes can be larger than the replica.fetch.max.bytes
                 Key: KAFKA-1844
                 URL: https://issues.apache.org/jira/browse/KAFKA-1844
             Project: Kafka
          Issue Type: Bug
            Reporter: Sriharsha Chintalapani
            Assignee: Sriharsha Chintalapani


This bug is related to KAFKA-1273. Kaka Broker on startup checks to see if the configured replica.fetch.max.bytes >= message.max.bytes. But users can override message.max.bytes per topic and there is no such validation happening for per topic message.max.bytes. If the users configured message.max.bytes > replica.fetch.max.bytes , followers won't be able to fetch data.
[~junrao] suggested " I was thinking that one way is to just disallow customizing max.message.size per topic. Such customization may break downstream consumers like MirrorMaker. I am not sure if there is a strong use case for the per topic customization."
