-------------------------------

Prashanth,

Thanks for signing up for this jira. One thing that I realized is that it may be a bit hard to do this jira and kafka-343 (moving leader election logic to controller) independently. This is because (1) a failed broker could embed a controller and therefore it's bit hard to separate out the testing of broker failure and controller failure; (2) some of the logic in controller failover can be shared with the leader election logic in controller. Since Yang already started working on kafka-343, it's probably better if he takes on this jira as well. Do you think that you could pick up one of the following jiras instead? Sorry about that.

KAFKA-330: Delete topic support
KAFKA-369: remove ZK dependency on producer
KAFKA-288: rework java producer API
KAFKA-289: reuse TopicData when sending produce request
KAFKA-355: Move the highwatermark maintenance logic out of Log.
KAFKA-356: create a generic thread class
