When build streaming cube in kylin, I got an error tip.

[??????]

Hello??dear kyliners:


         Lately, We tried to create a streaming model 
in kylin ,which refer to doc "Cubing from Kafka(Near RT Streaming)" in 
kylin official website,
and  we created the model and cube successfully, but when build the cube, 
it appeared an error,like this:


"
ERROR [http-nio-7070-exec-9] controller.CubeController:398 : 
org.apache.kafka.clients.consumer.ConsumerConfig.configNames()Ljava/util/Set;
java.lang.NoSuchMethodError: 
org.apache.kafka.clients.consumer.ConsumerConfig.configNames()Ljava/util/Set;"






our environment:  kylin 2.6.3; kafka 2.0.0.


If you know where is the problem or you know how to solve it, please contact 
me, thank you very much!
