> Topic config：Configs for topic 'athena_8603' are leader.replication.throttled.replicas=9:7,9:6,10:8,10:7,8:6,8:5,11:9,11:8,follower.replication.throttled.replicas=9:13,10:0,8:15,11:14,retention.ms=86400000,delete.retention.ms=60000
>  
> Reassignment of replica athena_8603-1-15 is still in progress
>  
> When I reassigning the topic partition, I found that some tasks have been in progress, lasting more than ten hours. After investigation, it was found that ReplicaAlterLogDirsThread was running all the time and occupies a high CPU usage rate (Attachment 1).
> Check the thread information (Attachment 2) and find that the log data is being copied. Check the log directory (Attachment 3) and find that the index of the future directory is older than the original log. Is it because the configuration delete.retention.ms=60000 caused the data to be deleted while copying ? This causes the replication thread to get stuck. Is there any solution?
