Gwen Shapira commented on KAFKA-1809:
-------------------------------------
Quick summary of changes since [~jjkoshy] and [~junrao] review:
0. Removed SecurityProtocol from core
1. I noticed that I was not using security.protocol configuration on the
clients at all (even when testing upgrades), so I removed it
2. Registration to ZK failed if brokers were not configured with PLAINTEXT
protocol. Fixed this. Of course ZK consumers will not work in this state.
3. Following KAFKA-1501, I changed the way Processors figure out which security
protocol is used. I sent an email to mailing list explaining the new logic.
4. Also modified EndPoint to parse connection strings with negative port
numbers, since those are used in some tests
> Refactor brokers to allow listening on multiple ports and IPs

>
> The goal is to eventually support different security mechanisms on different
> ports.
> Currently brokers are defined as host+port pair, and this definition exists
> throughout the code-base, therefore some refactoring is needed to support
> multiple ports for a single broker.
> The detailed design is here:
