------------------------------
Summary: return all live brokers in TopicMetadataResponse
Key: KAFKA-1535
URL: https://issues.apache.org/jira/browse/KAFKA-1535
Project: Kafka
Issue Type: Improvement
Components: core
Affects Versions: 0.8.2
Reporter: Jun Rao
Currently, we only return the brokers that have assigned replicas for a topic
in TopicMetadataResponse. The new producer will use those brokers for
refreshing metadata. Now suppose that we stop all those brokers, copy all local
data to some new hosts and then restart those hosts (with the original broker
id). There is no way for the new producer to automatically get the information
about the new brokers since all old brokers are gone.
