Connect 10.57.137.131:9092 First

Re-connect the returned host.name = Centos7,

Finally, continue to connect advertised.host.name=centos77

In fact the above are all the same IP, if debugging different machines, Kafka server configuration file, please be careful to modify, do not use localhost

As the official document says, consumers connect to any valid node, request leader metadata, and the consumer simply drops the message to leader broker.

The producer connects to any of the Alive nodes and requests metadata about the
Leaders for the partitions of a topic. This allows the producer to put the message
Directly to the leads broker for the partition.
