Chia-Ping Tsai commented on KAFKA-10786:
----------------------------------------
Is this similar to https://issues.apache.org/jira/browse/KAFKA-9654? Could you
update kafka to the fixed version and then test it again?
> 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
> Priority: Blocker
> 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?
