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:
