Hi, team. Im using Kafka 0.8.1.1. I'm running 8 brokers on 4 machine. (2 brokers on 1 machine) and I have 3 topics each have 16 partitions and 3 replicas.
kafka-topics describe is Topic:topicCDR PartitionCount:16 ReplicationFactor:3 Configs:retention.ms =3600000 Topic: topicCDR Partition: 0 Leader: 3 Replicas: 3,1,2 Isr: 3,2 Topic: topicCDR Partition: 1 Leader: 4 Replicas: 4,2,3 Isr: 3,4,2 Topic: topicCDR Partition: 2 Leader: 5 Replicas: 5,3,4 Isr: 3,4,5 Topic: topicCDR Partition: 3 Leader: 6 Replicas: 6,4,5 Isr: 4,5,6 Topic: topicCDR Partition: 4 Leader: 7 Replicas: 7,5,6 Isr: 5,6,7 Topic: topicCDR Partition: 5 Leader: 8 Replicas: 8,6,7 Isr: 6,7,8 Topic: topicCDR Partition: 6 Leader: 1 Replicas: 1,7,8 Isr: 1,7,8 Topic: topicCDR Partition: 7 Leader: 2 Replicas: 2,8,1 Isr: 8,2 Topic: topicCDR Partition: 8 Leader: 3 Replicas: 3,2,4 Isr: 3,4,2 Topic: topicCDR Partition: 9 Leader: 4 Replicas: 4,3,5 Isr: 3,4,5 Topic: topicCDR Partition: 10 Leader: 5 Replicas: 5,4,6 Isr: 4,5,6 Topic: topicCDR Partition: 11 Leader: 6 Replicas: 6,5,7 Isr: 5,6,7 Topic: topicCDR Partition: 12 Leader: 7 Replicas: 7,6,8 Isr: 6,7,8 Topic: topicCDR Partition: 13 Leader: 8 Replicas: 8,7,1 Isr: 7,8 Topic: topicCDR Partition: 14 Leader: 8 Replicas: 1,8,2 Isr: 8,2 Topic: topicCDR Partition: 15 Leader: 2 Replicas: 2,1,3 Isr: 3,2 Topic:topicDEBUG PartitionCount:16 ReplicationFactor:3 Configs:retention.ms =3600000 Topic: topicDEBUG Partition: 0 Leader: 4 Replicas: 4,3,5 Isr: 3,4,5 Topic: topicDEBUG Partition: 1 Leader: 5 Replicas: 5,4,6 Isr: 4,5,6 Topic: topicDEBUG Partition: 2 Leader: 6 Replicas: 6,5,7 Isr: 5,6,7 Topic: topicDEBUG Partition: 3 Leader: 7 Replicas: 7,6,8 Isr: 6,7,8 Topic: topicDEBUG Partition: 4 Leader: 8 Replicas: 8,7,1 Isr: 7,8 Topic: topicDEBUG Partition: 5 Leader: 8 Replicas: 1,8,2 Isr: 8,2 Topic: topicDEBUG Partition: 6 Leader: 2 Replicas: 2,1,3 Isr: 3,2 Topic: topicDEBUG Partition: 7 Leader: 3 Replicas: 3,2,4 Isr: 3,4,2 Topic: topicDEBUG Partition: 8 Leader: 4 Replicas: 4,5,6 Isr: 4,5,6 Topic: topicDEBUG Partition: 9 Leader: 5 Replicas: 5,6,7 Isr: 5,6,7 Topic: topicDEBUG Partition: 10 Leader: 6 Replicas: 6,7,8 Isr: 6,7,8 Topic: topicDEBUG Partition: 11 Leader: 7 Replicas: 7,8,1 Isr: 7,8,1 Topic: topicDEBUG Partition: 12 Leader: 8 Replicas: 8,1,2 Isr: 8,2 Topic: topicDEBUG Partition: 13 Leader: 3 Replicas: 1,2,3 Isr: 3,2 Topic: topicDEBUG Partition: 14 Leader: 2 Replicas: 2,3,4 Isr: 3,4,2 Topic: topicDEBUG Partition: 15 Leader: 3 Replicas: 3,4,5 Isr: 3,4,5 Topic:topicTRACE PartitionCount:16 ReplicationFactor:3 Configs:retention.ms =3600000 Topic: topicTRACE Partition: 0 Leader: 5 Replicas: 5,8,1 Isr: 5,8,1 Topic: topicTRACE Partition: 1 Leader: 6 Replicas: 6,1,2 Isr: 6,1,2 Topic: topicTRACE Partition: 2 Leader: 7 Replicas: 7,2,3 Isr: 3,7,2 Topic: topicTRACE Partition: 3 Leader: 8 Replicas: 8,3,4 Isr: 3,4,8 Topic: topicTRACE Partition: 4 Leader: 1 Replicas: 1,4,5 Isr: 1,5,4 Topic: topicTRACE Partition: 5 Leader: 2 Replicas: 2,5,6 Isr: 5,6,2 Topic: topicTRACE Partition: 6 Leader: 3 Replicas: 3,6,7 Isr: 3,6,7 Topic: topicTRACE Partition: 7 Leader: 4 Replicas: 4,7,8 Isr: 4,7,8 Topic: topicTRACE Partition: 8 Leader: 5 Replicas: 5,1,2 Isr: 5,1,2 Topic: topicTRACE Partition: 9 Leader: 6 Replicas: 6,2,3 Isr: 3,6,2 Topic: topicTRACE Partition: 10 Leader: 7 Replicas: 7,3,4 Isr: 3,4,7 Topic: topicTRACE Partition: 11 Leader: 8 Replicas: 8,4,5 Isr: 4,5,8 Problem is one of my topic's ISR is not updating and keep failing to be preferred replica. more detail, broker 1 for topicDEBUG's ISR is not updating.
