Jun Rao commented on KAFKA-1778:
--------------------------------

[~anigam], yes, you will need to configure multiple (e.g., 2 or 3) brokers 
eligible to be the controller in this approach. In this approach, the 
controller is guaranteed to be those eligible brokers. This seems a bit better 
for use case (b) since it allows one to completely isolate the controller from 
the other brokers that take produce/consumer load. In your proposal, the 
controller may still be on a non-preferred broker.
