-------------------------------------
[~xiongqiwu] are you planning to work on this JIRA? If not, I could take a stab
at fixing it.
> enable kafka broker to remove orphan partitions automatically
> --------------------------------------------------------------
>
> Key: KAFKA-7362
> URL: https://issues.apache.org/jira/browse/KAFKA-7362
> Project: Kafka
> Issue Type: Improvement
> Components: core, log
> Reporter: xiongqi wu
> Assignee: xiongqi wu
> Priority: Major
>
> When partition reassignment removes topic partitions from a offline broker,
> those removed partitions become orphan partitions to the broker. When the
> offline broker comes back online, it is not able to clean up both data and
> folders that belong to orphan partitions. Log manager will scan all all dirs
> during startup, but the time based retention policy on a topic partition will
> not be kicked out until the broker is either a follower or a leader of the
> partition. In addition, we do not have logic to delete folders that belong
> to orphan partition today.
> Open this ticket to provide a mechanism (when enabled) to safely remove
> orphan partitions automatically.
