Labels: newbie (was: )
> Ability to cancel replica reassignment in progress
> --------------------------------------------------
>
> Key: KAFKA-1676
> URL: https://issues.apache.org/jira/browse/KAFKA-1676
> Project: Kafka
> Issue Type: New Feature
> Components: controller
> Affects Versions: 0.8.1.1
> Reporter: Ryan Berdeen
> Assignee: Neha Narkhede
> Labels: newbie
>
> I've had several situations where I have started a replica reassignment that I've needed to cancel before it completed.
> This has happened
> * when moving to a new broker that turns out to be running on an impaired server
> * if the extra replication hurts cluster performance
> * dealing with replication bugs in kafka, like KAFKA-1670
> * when a single replica reassignment is taking a long time, and I want to start more replica assignments without waiting for the current one to finish.
> For the first three cases, as a last resort I have deleted the {{/admin/reassign_partitions}} key from ZooKeeper and restarted the controller. I would like to be able to do this by signaling the controller to stop, and to leave the list of assignments as they exist at that moment.
