Navina Ramesh commented on SAMZA-458:
-------------------------------------

I meant add a "producer.close()" in flush() , when there is a send failure. 
Today, essentially what "stop()" does is to close the producer. In order to 
avoid repeated code, we called stop() on flush failure. 

> Close in KafkaSystemProducer should flush all source buffers

> I noticed that calling KafkaSystemProducer.stop does not flush any 
> outstanding messages in the sourceBuffers array. Calling close should flush 
> all buffers. Without this, shutting down can cause messages to be dropped.
