主题： Kafka broker failed to work when migrating the broker to another machine
Hi,
I set up a Kafka cluster with 5 brokers, with the broker ids 0, 1, 2, 3, 4.
I stop the node whose broke id is 4, and deploy a new broker in a new machine
with the broker id 4.
But I find the new broker failed to work, it never appears in ISR.
[zk: localhost:2181(CONNECTED) 3] ls /kafka/test2/brokers/ids
[3, 2, 1, 0, 4]
from zk, we can see the broker 4 has joined the cluster
[hadoop@slave01 bin]$ ./kafka-topics.sh --zookeeper 192.168.135.102/kafka/test2
--topic log_error --describe
Topic:log_error PartitionCount:1 ReplicationFactor:3 Configs:
Topic: log_error Partition: 0 Leader: 0 Replicas: 1,4,0
Isr: 0,1
we can see 4 never appear in ISR
below is the content in kafka log dir:
