   @sijie Thanks for your reply, but I'm still not clear. 
   
   For the multi-clusters environment like I given in my previous question, suppose I have a domain name named pulsar.east-china.com which is provided for pulsar client to use, so how should I set the A record in DNS server for pulsar.east-china.com? I don't think it can work if I config DNS as follows:
   pulsar.east-china.com    IN  A  B1-ip-address
   pulsar.east-china.com    IN  A  B2-ip-address
   pulsar.east-china.com    IN  A  B3-ip-address
   
   That's because none of brokers has the instance-wide metadata. Let's think of this case, if a pulsar client is created with pulsar.east-china.com and the DNS server return B2-ip-address to the client, then it will make a connection with B2. If the client continue to create a Consumer on T3 which is owned by B3, B2 will not find the topic and return an error?
   
   For a single cluster environment, if I use the built-in discovery service, what address should I use for web-service-url and broker-service-url while executing initialize-cluster-metadata?
