I get the same NPE issue in `Spark 1.4.1` also. I'm not sure what's wrong
(yet) as my spark streaming job was running fine printing out `Array[Byte]`
data, but after I added a custom decoder (Avro to my class `Swipe`) it keeps
spitting the NPE error (`consumer` is `null`). Any hints on what could be the
root
cause?
`val swipes = KafkaUtils.createDirectStream[Array[Byte], Array[Byte],
DefaultDecoder, DefaultDecoder](ssc, kafkaParams, topics)` works, but
`val swipes = KafkaUtils.createDirectStream[Array[Byte], Swipe,
DefaultDecoder, SwipeDecoder](ssc, kafkaParams, topics)` doesn't. In that
aspect the NPE is sorta misleading (maybe).
