Igor Soarez resolved KAFKA-16624. --------------------------------- Resolution: Fixed > Don't generate useless PartitionChangeRecord on older MV > -------------------------------------------------------- > > Key: KAFKA-16624 > URL: https://issues.apache.org/jira/browse/KAFKA-16624 > Project: Kafka > Issue Type: Bug > Reporter: Colin McCabe > Assignee: Colin McCabe > Priority: Minor > > Fix a case where we could generate useless PartitionChangeRecords on metadata > versions older than 3.6-IV0. This could happen in the case where we had an > ISR with only one broker in it, and we were trying to go down to a fully > empty ISR. In this case, PartitionChangeBuilder would block the record to > going down to a fully empty ISR (since that is not valid in these pre-KIP-966 > metadata versions), but it would still emit the record, even though it had no > effect. -- This message was sent by Atlassian Jira (v8.20.10#820010)
