Jason Gustafson updated KAFKA-10143: ------------------------------------ Summary: Add integration testing ensuring that the reassignment tool can change replication quota with rebalance in progress (was: Can no longer change replication throttle with reassignment tool) > Add integration testing ensuring that the reassignment tool can change > replication quota with rebalance in progress > ------------------------------------------------------------------------------------------------------------------- > > Key: KAFKA-10143 > URL: https://issues.apache.org/jira/browse/KAFKA-10143 > Project: Kafka > Issue Type: Bug > Components: core > Affects Versions: 2.6.0 > Reporter: Jason Gustafson > Assignee: Jason Gustafson > Priority: Major > Fix For: 2.7.0, 2.6.1 > > > Previously we could use --execute with the --throttle option in order to > change the quota of an active reassignment. We seem to have lost this with > KIP-455. The code has the following comment: > {code} > val reassignPartitionsInProgress = zkClient.reassignPartitionsInProgress() > if (reassignPartitionsInProgress) { > // Note: older versions of this tool would modify the broker quotas > here (but not > // topic quotas, for some reason). This behavior wasn't documented in > the --execute > // command line help. Since it might interfere with other ongoing > reassignments, > // this behavior was dropped as part of the KIP-455 changes. > throw new > TerseReassignmentFailureException(cannotExecuteBecauseOfExistingMessage) > } > {code} > Seems like it was a mistake to change this because it breaks compatibility. > We probably have to revert. At the same time, we can make the intent clearer > both in the code and in the command help output. -- This message was sent by Atlassian Jira (v8.3.4#803005)
