Matthias J. Sax commented on KAFKA-6304: ---------------------------------------- Moving all major/minor/trivial tickets that are not merged yet out of 2.2 release. > The controller should allow updating the partition reassignment for the > partitions being reassigned > --------------------------------------------------------------------------------------------------- > > Key: KAFKA-6304 > URL: https://issues.apache.org/jira/browse/KAFKA-6304 > Project: Kafka > Issue Type: Improvement > Components: controller, core > Affects Versions: 1.0.0 > Reporter: Jiangjie Qin > Priority: Major > Fix For: 2.2.0 > > > Currently the controller will not process the partition reassignment of a > partition if the partition is already being reassigned. > The issue is that if there is a broker failure during the partition > reassignment, the partition reassignment may never finish. And the users may > want to cancel the partition reassignment. However, the controller will > refuse to do that unless user manually deletes the partition reassignment zk > path, force a controller switch and then issue the revert command. This is > pretty involved. It seems reasonable for the controller to replace the > ongoing stuck reassignment and replace it with the updated partition > assignment. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
