Hello, I have a 6 broker cluster, configured with auto.leader.rebalance.enable=false. The broker ids are 1 thru 6.
I have about 160 partitions for which I assigned the replicas to be 1,2,3 (1 is the leader). When broker-2 underwent a controlled shutdown, the 'kafka-topics.sh -describe' command showed the ISRs for these partitions to be 1,3, which is an expected outcome. In case broker-2 is never going to come back alive, will Kafka be able to automatically elect a new follower in the place of broker-2? In other words, just like how a new leader is elected for a partition when its leader goes down, is there a possibility that a new follower is chosen from the list of available brokers? I understand that I can manually specify a new replica set and use kafka-reassign-partition.sh to execute the reassignment. But I am looking to see if Kafka does any follower assignment by itself. Thanks, Buvana
