Kia ora, I am rather bemused by this one, I'll admit. Kafka version 2.4.0. We've been migrating topic-partitions from old broker machines to new brokers, have redistributed replicas evenly across the new brokers, removed the old brokers, and tried to run a preferred leader election.
And when I did that, I got a "LeaderElectionNotNeededException", which I really disagree with, as two brokers out of six have 41% of partition leaders. I wonder if it's rack awareness messing with us or something? We are running two brokers in three AZs/racks with correctly configured rack.ids, but what are the origins of a "LeaderElectionNotNeededException"? And for the love of God, where is the parameter in the admin client for "I significantly disagree". Kind regards, Liam Clarke-Hutchinson
