>
> There are several method call in kafka sink with no timeout arguments, in
> some cases, kafka sink will await forever if no interruption.
> For example，
> case 1 : When we stop kafka sink, it will call producer.close() without
> timeout arguement. This will cause another close method in producer with
> timeout arguement as (Long.MAX_VALUE, TimeUnit.MILLISECONDS). Then it will
> wait producer's IOThread exited, if the IOThread can't exit normally, kafka
> sink will block all the time and there is no effect of kill -TERM.
> case 2 : When an uncaught exception happened such as Correlation ID does not
> match in Kafka Producer Sender thread, the sender will lost this request. If
> we call producer.flush(), there is a await() without timeout arguement, kafka
> sink will block all the time except restart it.
> case 3 : Like case 2, when we call future.get() without timeout arguement but
> the request in Kafka Producer lost, kafka sink will also block all the time.
