Moved the prefered location and consumer creation strategies to an explicit
interface, let me know if that's more usable from your point of view.
Scala api looks like
KafkaUtils.createDirectStream[String, String](
ssc,
PreferConsistent,
Subscribe[String, String](topics, kafkaParams)
)
For starting from given offsets, the subscribe line would look like
FromOffsets[String, String](offsets,
Subscribe[String, String](topics, kafkaParams))
so that starting offsets can be used with arbitrary other setup strategies.
The ConsumerStrategy interface is public so that people can do arbitrary
setup if need be.
Java api looks like
JavaInputDStream<ConsumerRecord<String, String>> istream2 =
KafkaUtils.createDirectStream(
ssc,
String.class,
String.class,
PreferConsistent.create(),
Subscribe.create(String.class, String.class, Arrays.asList(topic2),
kafkaParams2)
);
