There is no one leader in kafka cluster for the a topic's partition, there
could be a different leader for each partition,
./bin/kafka-topics --describe --topic topic-a --bootstrap-server localhost:9092
Topic:topic-a PartitionCount:4 ReplicationFactor:2 Configs:
Topic: topic-a Partition: 0 Leader: 0 Replicas: 0,1 Isr: 0,1
Topic: topic-a Partition: 1 Leader: 0 Replicas: 0,1 Isr: 0,1
Topic: topic-a Partition: 2 Leader: 0 Replicas: 0,1 Isr: 0,1
Topic: topic-a Partition: 3 Leader: 0 Replicas: 0,1 Isr: 0,1
./bin/kafka-topics --describe --topic topic-b --bootstrap-server localhost:9092
Topic:topic-b PartitionCount:4 ReplicationFactor:2 Configs:
Topic: topic-b Partition: 0 Leader: 1 Replicas: 1,0 Isr: 1,0
Topic: topic-b Partition: 1 Leader: 2 Replicas: 2,1 Isr: 2,1
Topic: topic-b Partition: 2 Leader: 1 Replicas: 1,2 Isr: 1,2
Topic: topic-b Partition: 3 Leader: 2 Replicas: 2,1 Isr: 2,1
There is one kafka controller which is the "leader" of cluster,
You can find out which is the controller by the following command
./bin/zookeeper-shell.sh [ZK_IP] get /controller
