Billy Liu commented on KYLIN-3393:
----------------------------------
[~wuyingjun], Kylin does not depend on the Kafka Server, but the Kafka Client.
So you do not need to install Kafka into kylin node, but copy the necessary
client library. That's the same thing we are doing with Hadoop/Hive/HBase as
Shaofeng said. Kylin keeps the dependency libraries out of the package to make
it more compatible with the environment. If Kylin ships the fixed-version
client libraries in binary, you have to recompile everything if the client
library has conflicts with the server side.
