             Summary: MirrorMaker crashes on Corrupted Message
                 Key: KAFKA-3772
                 URL: https://issues.apache.org/jira/browse/KAFKA-3772
             Project: Kafka
          Issue Type: Bug
          Components: core
    Affects Versions: 0.9.0.1
            Reporter: James Ranson


We recently came across an issue where a message on our source kafka cluster became corrupted. When MirrorMaker tried to consume this message, the thread crashed and caused the entire process to also crash. Each time we attempted to restart MM, it crashed on the same message. There is no information in the MM logs about which message it was trying to consume (what topic, what offset, etc). So the only way we were able to get past the issue was to go into the zookeeper tree for our mirror consumer group and increment the offset for every partition on every topic until the MM process could start without crashing. This is not a tenable operational solution. MirrorMaker should gracefully skip corrupt messages since they will never be able to be replicated anyway.
