-------------------------------------

Hi BKRV:
I see that 'ClusterId read in ZooKeeper is null' in your error log.
Maybe there are some error of you hbase-site.xml, you can check it.
If you still can't solve this problem, you can send email to Apache Kylin Mailing List for
help, this below document can help you subscribe Kylin mailing list.
