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

             Summary: Upgrade Snappy to fix snappy decompression errors
                 Key: KAFKA-3789
                 URL: https://issues.apache.org/jira/browse/KAFKA-3789
             Project: Kafka
          Issue Type: Bug
          Components: core
    Affects Versions: 0.10.0.0
            Reporter: Grant Henke
            Assignee: Grant Henke
            Priority: Critical
             Fix For: 0.10.0.1


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.
