Jiangjie Qin created KAFKA-4340:
-----------------------------------

             Summary: Change the default value of 
log.message.timestamp.difference.max.ms to the same as log.retention.ms
                 Key: KAFKA-4340
                 URL: https://issues.apache.org/jira/browse/KAFKA-4340
             Project: Kafka
          Issue Type: Improvement
          Components: core
    Affects Versions: 0.10.1.0
            Reporter: Jiangjie Qin
            Assignee: Jiangjie Qin
             Fix For: 0.10.1.1


[~junrao] brought up the following scenario: 

If users are pumping data with timestamp already passed log.retention.ms into 
Kafka, the messages will be appended to the log but will be immediately rolled 
out by log retention thread when it kicks in and the messages will be deleted. 

To avoid this produce-and-deleted scenario, we can set the default value of 
log.message.timestamp.difference.max.ms to be the same as log.retention.ms.
