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

Thank you for your suggestions! When I tried with those plans you provided, I can find thekafka-client-{version}.jar and it also can be loaded by kylin. But when we restart the kylin, and recreate the model and cube??it also goes wrong with the same error message.

Hi, the images cannot be loaded. As your description, may I ask do these two clusters use different name service?  If they use the same name service may cause some problems. Hope the following article can be helpful. http://kylin.apache.org/blog/2016/06/10/standalone-hbase-cluster/
