Sample Kafka Producer/Consumer example in Scala

[prashant amar <am...@gmail.com>]

Hello All

I have been attempting to build an end-to-end example of producer with
multiple consumers using scala.
I managed to build a producer, but when I attempt to build a consumer the
following statement causes the scala REPL to block/hang

val consumerMap = consumer.createMessageStreams(topicCountMap)

Am I missing anything here?

Can anybody please point me to a simple producer with multiple consumers
example in scala?

*Please do not point me to ConsumerConsumer or MirrorMaker as both of them
are fairly complex to even look at (given that I am a novice scala
programmer)*

Any help will be appreciated?

Thanks in advance
Amar

What you did is correct. Could you try running it as a standalone app and
not from scala REPL?

Thanks,
