Jun Rao commented on KAFKA-1535: -------------------------------- A solution is to return all live brokers (in metadata cache) in TopicMetadataResponse. This doesn't change the wire protocol, just the list of brokers returned. > 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 > Labels: newbie > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
