             Summary:  ReplicaAlterLogDirsThread gets stuck during the reassignment of Kafka partition
                 Key: KAFKA-10786
                 URL: https://issues.apache.org/jira/browse/KAFKA-10786
             Project: Kafka
          Issue Type: Bug
          Components: log
    Affects Versions: 2.0.0
            Reporter: nick song
         Attachments: attachment 1.png, attachment 2.png, attachment 3.png

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?
