Sasaki Toru commented on SPARK-20052:
-------------------------------------

My explain is not good, sorry.

This ticket is related to SPARK-20050.
In JobGenerate#stop, it will wait for finishing all batches after 
InputDStream#stop called when graceful shutdown is enable,
but Kafka 0.10 DirectStream should commit offset after processing all batches.

So I thought more process(I explained this "closing process") is needed after 
processing all batches.


> Some InputDStream needs closing processing after processing all batches when 
> graceful shutdown

> Some class extend InputDStream needs closing processing after processing all 
> batches when graceful shutdown enabled.
> (e.g. When using Kafka as data source, need to commit processed offsets to 
> Kafka Broker)
> InputDStream has method 'stop' to stop receiving data, but this method will 
> be called before processing last batches generated for graceful shutdown.
