Prashanth Menon updated KAFKA-329:
----------------------------------

    Attachment: KAFKA-329-DRAFT-v2.patch

Thanks for the review, Jun.  New draft is attached incorporating both your suggestions, though
it's still in draft and not final.  My only concern, and I'm not sure if it's my machine or
not, but the ZooKeeperConsumerConnectorTest takes an unusually long time to run and throws
exceptions intermittently.  

I'll take a final walkthrough tomorrow, along with any additional suggestions and submit another
final patch for review.

> Currently in 0.8, all brokers register a watch on /brokers/topics and /brokers/topics/[topic]
for all topics in a Kafka cluster. The watches are required to discover new topics. 
> There is another way this can be achieved, as proposed here - https://cwiki.apache.org/confluence/display/KAFKA/Kafka+replication+detailed+design+V2#KafkareplicationdetaileddesignV2-Createtopic
> Basically, the create-topic admin command sends start-replica state change request to
all brokers in the assigned replicas list.
