Jay Kreps commented on KAFKA-1238:
----------------------------------
Yeah arguably the server should just return all the brokers. I think the only
argument against that was supporting very very large clusters.
1. I guess I meant that more as a "this should not happen" exception, rather
than handle it I kind of just want to proceed with the testing and fix these
cases.
2. Yeah I was going to wait on the outcome of the discussion on request
protocol serialization to establish a pattern there. Not many people chimed in
on that one.
