Cody, thanks for the response.

 

So Kafka direct stream actually has consumer on both the driver and executor? 
Can you please provide more details? Thank you very much!

its set to none for the executors, because otherwise they wont do exactly what 
the driver told them to do.

 

you should be able to set up the driver consumer to determine batches however 
you want, though.

Hi,

 

I want to read the existing Kafka messages and then subscribe new stream 
messages. 

But I find "auto.offset.reset" property is always set to "none" in KafkaUtils. 
Does that mean I cannot specify "earliest" property value when create direct 
stream?

Thank you!
