[jira] [Created] (KAFKA-2523) New consumer doesn't check magic version

Jay Kreps created KAFKA-2523:
--------------------------------

             Summary: New consumer doesn't check magic version
                 Key: KAFKA-2523
                 URL: https://issues.apache.org/jira/browse/KAFKA-2523
             Project: Kafka
          Issue Type: Bug
            Reporter: Jay Kreps
            Priority: Blocker


The new consumer should be checking that messages it reads are in the format it expects (and give a sane error message otherwise) rather than just randomly reading other formats and running out of memory or getting cryptic errors. This should be a one-line fix.

It is important if we're thinking of changing the message format since you need the proper check in the versions BEFORE the version where you make the change so sane errors occur when the change eventually does happen.
