----------------------------------
Assignee: dengziming
> Reassignment tool sets throttles incorrectly when overriding a reassignment
> ---------------------------------------------------------------------------
>
> Key: KAFKA-10779
> URL: https://issues.apache.org/jira/browse/KAFKA-10779
> Project: Kafka
> Issue Type: Bug
> Reporter: Jason Gustafson
> Assignee: dengziming
> Priority: Major
>
> The logic in `ReassignPartitionsCommand.calculateProposedMoveMap` assumes
> that adding replicas are not included in the replica set returned from
> `Metadata` or `ListPartitionReassignments`. This is evident in the test case
> `ReassignPartitionsUnitTest.testMoveMap`. Because of this incorrect
> assumption, the move map is computed incorrectly which can result in the
> wrong throttles being applied. As far as I can tell, this is only an issue
> when overriding an existing reassignment.
