Yang Ye updated KAFKA-473:
--------------------------
Attachment: kafka_473_v1.diff
1. create a utility function "getTopicMetadata" in Utils.scala to get topic
metadata, and let the BrokerPartitionInfo and leaderFinderThread use it
2. a function getConsumerTopicMaps() in zkUtils() is never used, remove it.
3. potentially still use the function in consumer rebalancing
> Use getMetadata Api in ZookeeperConsumerConnector

> Currently, ZookeeperConsumerConnector gets topic metadata from ZK directly.
> It's better to use the getMetadata Api since it's batched. This is especially
> helpful if the consumer client is in a different data center.
