David Arthur updated KAFKA-15109: --------------------------------- Affects Version/s: 3.6.0 (was: 3.5.0) > ISR shrink/expand issues on ZK brokers during migration > ------------------------------------------------------- > > Key: KAFKA-15109 > URL: https://issues.apache.org/jira/browse/KAFKA-15109 > Project: Kafka > Issue Type: Bug > Components: kraft, replication > Affects Versions: 3.6.0 > Reporter: David Arthur > Priority: Critical > > KAFKA-15021 introduced a new controller behavior that avoids increasing the > leader epoch during the controlled shutdown scenario. This prevents some > unnecessary thrashing of metadata and threads on the brokers and clients. > While a cluster is in a KIP-866 migration and has a KRaft controller with ZK > brokers, we cannot employ this leader epoch bump avoidance. The ZK brokers > must have the leader epoch bump in order for ReplicaManager to react to the > LeaderAndIsrRequest. -- This message was sent by Atlassian Jira (v8.20.10#820010)
