Shaofeng SHI commented on KYLIN-3393:
-------------------------------------

Hi yingjun, I undrestand your point. But, to connect with Kafka server, you need install the
client in the Kylin node before run it, this is the same as Hive, HBase and other services.
The problem you are facing might be, your cluster default installes Hadoop/Hive/HBase clients
on each node, but no Kafka clients.

> You need hava  KAFKA environment and set “KAFKA_HOME” environment variable when
building streaming cube, or else you can not submit a streaming cube building job, like pic
1;
> After we change the kafka dependency scope mode described in the KYLIN-3393.patch , we
can build streaming cube without a kafka environment in the kylin service node successfully,
like pic 2;
