             Summary: Display reasonable exception message if could not find 
kafka dependency for streaming build 
                 Key: KYLIN-2263
                 URL: https://issues.apache.org/jira/browse/KYLIN-2263
             Project: Kylin
          Issue Type: Improvement
          Components: Web 
    Affects Versions: v1.6.0
            Reporter: Billy Liu
            Assignee: Billy Liu
            Priority: Minor


Kafka is optional dependency for Kylin install. But is mandatory for streaming 
build. Currently, if no KAFKA_HOME exported, the build will show "Error", but 
without any more detail message. It's not convenient for new user.
