[jira] [Created] (KAFKA-1535) return all live brokers in TopicMetadataResponse

Jun Rao created KAFKA-1535:
------------------------------

             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.
