I am a new learner of kafka.But what make me confused is that there seems to be two packages of kafka clients.
One is kafka.javaapi.* like
import kafka.javaapi.producer.Producer;
import kafka.producer.KeyedMessage;
import kafka.producer.ProducerConfig;
the other is org.apache.kafka.*. like
import org.apache.kafka.clients.producer.KafkaProducer<K,V>
which is shown is page http://kafka.apache.org/082/javadoc/index.html?org/apache/kafka/clients/producer
I don't know what's their differences.
