--------------------------------------
Any update on this? We are seeing the effect of this issue during rolling restarts of kafka brokers combined with CruiseControl auto-balancer running and moving offline partitions. thanks!

> 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.
