> snappy-java recently fixed a bug where parsing the MAGIC HEADER was being handled incorrectly: https://github.com/xerial/snappy-java/issues/142
> This issue caused "unknown broker exceptions" in the clients and prevented these messages from being appended to the log when messages were written using snappy c bindings in clients like librdkafka or ruby-kafka and read using snappy-java in the broker.   
> The related librdkafka issue is here: https://github.com/edenhill/librdkafka/issues/645
> I am able to regularly reproduce the issue with librdkafka in 0.10 and after upgrading snappy-java to 1.1.2.6 the issue is resolved.
