Kafka调整ISR顺序

查看topic详情

$ kafka-topics.sh --bootstrap-server 192.168.32.187:9092 --describe --topic test01
Topic: test01   TopicId: 1m19YRC3S9SIe2zvJQLMIw PartitionCount: 3       ReplicationFactor: 2    Configs: segment.bytes=1073741824
        Topic: test01   Partition: 0    Leader: 2       Replicas: 2,0   Isr: 2,0
        Topic: test01   Partition: 1    Leader: 1       Replicas: 1,2   Isr: 2,1
        Topic: test01   Partition: 2    Leader: 0       Replicas: 0,1   Isr: 0,1

调整ISR顺序

$ zkCli.sh -server 192.168.32.187:2181
[zk: 192.168.32.187:2181(CONNECTED) 0] get /kafka/brokers/topics/test01/partitions/1/state
{"controller_epoch":14,"leader":1,"version":1,"leader_epoch":2,"isr":[2,1]}
[zk: 192.168.32.187:2181(CONNECTED) 1] set /kafka/brokers/topics/test01/partitions/1/state {"controller_epoch":14,"leader":1,"version":1,"leader_epoch":2,"isr":[1,2]}

更新元数据

[zk: 192.168.32.187:2181(CONNECTED) 2] create /kafka/isr_change_notification/isr_change_0000000001 {"version":1,"partitions":[{"topic":"test01","partition":1}]}
Created /kafka/isr_change_notification/isr_change_0000000001

• 需要修改 data 里面的内容
• 创建好该节点，更新完后马上又被controller删除。

验证

$ kafka-topics.sh --bootstrap-server 192.168.32.187:9092 --describe --topic test01
