Hello, I am running 3 brokers, one zookeeper and producer all on separate machine. I am also sending very low load around 6K msg/sec. Each msg is around 150 bytes only. I ran the load for only 5 minutes and during this time, I see leadership chained very often.
I created 3 partitions. Here leadership for each partitions changed. All 3 brokers are running perfectly fine. No broker is down. Could someone let me know why kafka leadership changed very often. Initially: Topic:mmetopic1PartitionCount:3 ReplicationFactor:3 Configs: Topic: mmetopic1Partition: 0 Leader: 2Replicas: 2,3,1 Isr: 2,3,1 Topic: mmetopic1Partition: 1 Leader: 3Replicas: 3,1,2 Isr: 3,1,2 Topic: mmetopic1Partition: 2 Leader: 1Replicas: 1,2,3 Isr: 1,2,3 Changed to: Topic:mmetopic1PartitionCount:3 ReplicationFactor:3 Configs: Topic: mmetopic1Partition: 0 Leader: 3Replicas: 2,3,1 Isr: 3,1,2 Topic: mmetopic1Partition: 1 Leader: 3Replicas: 3,1,2 Isr: 3,1,2 Topic: mmetopic1Partition: 2 Leader: 1Replicas: 1,2,3 Isr: 1,3,2 Changed to: Topic:mmetopic1PartitionCount:3 ReplicationFactor:3 Configs: Topic: mmetopic1Partition: 0 Leader: 1Replicas: 2,3,1 Isr: 1,2,3 Topic: mmetopic1Partition: 1 Leader: 1Replicas: 3,1,2 Isr: 1,2,3 Topic: mmetopic1Partition: 2 Leader: 2Replicas: 1,2,3 Isr: 2,1,3 Changed to: Topic:mmetopic1PartitionCount:3 ReplicationFactor:3 Configs: Topic: mmetopic1Partition: 0 Leader: 3Replicas: 2,3,1 Isr: 3,1,2 Topic: mmetopic1Partition: 1 Leader: 3Replicas: 3,1,2 Isr: 3,1,2 Topic: mmetopic1Partition: 2 Leader: 1Replicas: 1,2,3 Isr: 1,3,2 Thanks, Lokesh
