Github user srdo commented on the issue: https://github.com/apache/storm/pull/2181 @tiodollar Nice find. The fix is not workable though. We need to update OffsetManager to handle that the commit offset should be the last processed offset +1, as per the Kafka docs for commitSync: "The committed offset should be the next message your application will consume, i.e. lastProcessedMessageOffset + 1". Would you like to take a look at fixing this? I'd also be happy to take a stab at it.
