---------------------------------------
Summary: TopicMetadataResponse.brokers not read in scala producer?
Key: KAFKA-1553
URL: https://issues.apache.org/jira/browse/KAFKA-1553
Project: Kafka
Issue Type: Bug
Components: producer
Affects Versions: 0.8.2
Reporter: Nicolae Marasoiu
Assignee: Jun Rao
I searched again and I do think that topicMetadataResponse.brokers is not read
in Scala Producer, or I have not found where it is. (In the java producer it
does seem used on the other hand).
The producer seems to only parse its static configuration (properties file on
key metadata.broker.list on disk stating initial broker list), and cache it in
BrokerPartitionInfo. It never updates that broker list cache when it receives a
metadata response!
It really seems that only that statically configured metadata.broker.list is
ever queried for metadata, not only initially but at any time e.g. this list is
never refreshed with the brokers listed in the topic metadata response.
