> Interrupting a thread where a Producer is in use can cause unexpected
> behavior. In the case of an async type producer, interrupting the producer
> thread will like lead to a QueueFullException with the default configuration
> (see
> https://github.com/apache/kafka/blob/0.8.1.1/core/src/main/scala/kafka/producer/Producer.scala#L105-L112
> )
> This obviously can't be safely be used in client code to determine if the
> thread was interrupted because the async producer's message queue may simply
> be backed up. It's important to be able to distinguish between interrupts vs
> full queues so client thread pools can be shutdown properly etc.
> In the case of a sync producer, there's the possibility an
> InterruptedException will bubble up out of Producer.send. This will likely
> result in an UndeclaredThrowableException in Java code -- this is more
> helpful than a QueueFullException, but it's still somewhat awkward.
