Jun Rao updated KAFKA-1882:
---------------------------
Status: In Progress (was: Patch Available)
> Create extendable channel interface and default implementations
> ---------------------------------------------------------------
>
> Key: KAFKA-1882
> URL: https://issues.apache.org/jira/browse/KAFKA-1882
> Project: Kafka
> Issue Type: Sub-task
> Components: security
> Reporter: Gwen Shapira
> Assignee: Gwen Shapira
> Priority: Blocker
> Fix For: 0.8.3
>
>
> For the security infrastructure, we need an extendible interface to replace
> SocketChannel.
> KAFKA-1684 suggests extending SocketChannel itself, but since SocketChannel
> is part of Java's standard library, the interface changes between different
> Java versions, so extending it directly can become a compatibility issue.
> Instead, we can implement a KafkaChannel interface, which will implement
> connect(), read(), write() and possibly other methods we use.
> We will replace direct use of SocketChannel in our code with use of
> KafkaChannel.
> Different implementations of KafkaChannel will be instantiated based on the
> port/SecurityProtocol configuration.
> This patch will provide at least the PLAINTEXT implementation for
> KafkaChannel.
> I will validate that the SSL implementation in KAFKA-1684 can be refactored
> to use a KafkaChannel interface rather than extend SocketChannel directly.
> However, the patch will not include the SSL channel itself.
> The interface should also include setters/getters for principal and remote
> IP, which will be used for the authentication code.
