[~lindong] I believe this might also be a fix for 
https://issues.apache.org/jira/browse/KAFKA-6188 .

> synchronize Log modification between delete cleanup and async delete
> --------------------------------------------------------------------
>                 Key: KAFKA-6701
>                 URL: https://issues.apache.org/jira/browse/KAFKA-6701
>             Project: Kafka
>          Issue Type: Bug
>            Reporter: Sumant Tambe
>            Assignee: Sumant Tambe
>            Priority: Major
> Kafka broker crashes without any evident disk failures 
> From [~becket_qin]: This looks a bug in kafka when topic deletion and log 
> retention cleanup happen at the same time, the log retention cleanup may see 
> ClosedChannelException after the log has been renamed for async deletion.
> The root cause is that the topic deletion should have set the isClosed flag 
> of the partition log to true and the retention should not bother to do the 
> old log segments deletion when the log is closed.
