Zhang Yue commented on KYLIN-2369:
----------------------------------
Sorry for this.
Thx,I have solved the problem,I installed Kafka on a machine outside of Hadoop
Cluster,Then I realized this mistake.
After I reinstall the Kafka into Hadoop Cluster then export kafka environment
on every node and reboot the Kylin,the Streaming problems solved.
Thx
