> In KAFKA-1690, we are adding the SSL support at Selector. However, there are
> still a few places where we use BlockingChannel for inter-broker
> communication. We need to replace those usage with Selector/NetworkClient to
> enable inter-broker communication over SSL. Specially, BlockingChannel is
> currently used in the following places.
> 1. ControllerChannelManager: for the controller to propagate metadata to the
> brokers.
> 2. KafkaServer: for the broker to send controlled shutdown request to the
> controller.
> 3. -AbstractFetcherThread: for the follower to fetch data from the leader
> (through SimpleConsumer)- moved to KAFKA-2440
