   @jinyanhui2008 mapedFileSizeCommitLog跟保留时间没有直接关系,但是在你的情况中可能是连一个commitlog都没有写满,其余的两个参数建议配置还是一下,[参考中文文档](http://rocketmq.cloud/zh-cn/docs/bestpractice-broker.html),是否重复消费跟消费端的配置也有关系,比如是否是新的consumer group,包括消费起始位置等,RocketMQ即使在新的consumer group的情况下,如果消息量不大尚在内存中,也会从头消费,用以避免消息丢失。
   Issue一般用来做bug report以及feature request,所以有问题还是希望在邮件列表里面搜索提问,[邮件列表地址](https://rocketmq.apache.org/about/contact/),所以我先关掉这个issue,有问题的话也可以再打开。
