> ------------------------------------------------------------------------------------
>
> Key: KAFKA-15122
> URL: https://issues.apache.org/jira/browse/KAFKA-15122
> Project: Kafka
> Issue Type: Task
> Affects Versions: 3.4.0
> Reporter: Mickael Maison
> Priority: Major
> Fix For: 3.5.0
>
>
> # Start a broker with 2 log directories
> # Create a topic-partition
> Metrics with the following names are created:
> kafka.log:type=Log,name=Size,topic=<TOPIC>,partition=0
> # Using kafka-reassign-partitions move that partition to the other log
> directory
> A tag is-future=true is added to the existing metrics,
> kafka.log:type=Log,name=Size,topic=<TOPIC>,partition=0,is-future=true
> # Using kafka-reassign-partitions move that partition back to its original
> log directory
> The metrics are deleted!
> I don't expect the metrics to be renamed during the first reassignment. The
> metrics should not be deleted during the second reassignment, the topic still
> exists. Restarting the broker resolves the issue.
