Onur Karaman updated KAFKA-6146: -------------------------------- Description: We currently enqueue a PreferredReplicaLeaderElection controller event in PreferredReplicaElectionHandler's handleCreation, handleDeletion, and handleDataChange. We really only need to enqueue the event and re-register the exist watch on after preferred replica leader election completes. (was: Currently, after the PreferredReplicaElectionZNode is removed, we don't register the exist watcher on the path again. This means that future preferred replica election event will be missed.) > re-register the exist watch on PreferredReplicaElectionZNode after the > preferred leader election completes > ----------------------------------------------------------------------------------------------------------- > > Key: KAFKA-6146 > URL: https://issues.apache.org/jira/browse/KAFKA-6146 > Project: Kafka > Issue Type: Sub-task > Affects Versions: 1.1.0 > Reporter: Jun Rao > Fix For: 1.1.0 > > > We currently enqueue a PreferredReplicaLeaderElection controller event in > PreferredReplicaElectionHandler's handleCreation, handleDeletion, and > handleDataChange.
