修改server.properties，然后将每个节点的kafka重启即可解决。
vim config/server.properties
#注释打开并把值修改成host
# Hostname the broker will advertise to producers and consumers. If not set, it uses the
# value for "host.name" if configured. Otherwise, it will use the value returned from
# java.net.InetAddress.getCanonicalHostName().
advertised.host.name=hs03
查看集群是否有broker没有运行
#进入zookeeper客户端
zookeeper-shell.sh hs01:2181,hs02:2181,hs03:2181
#查看状态
ls /brokers/ids
