EMR 5.28 issue when cube build

[Raghu Ram Reddy Medapati <ra...@gmail.com>]

I setup kylin 3.0(latest) on EMR 5.28.
I have created a separate hive/yarn/spark EMR cluster, a Hbase EMR cluster and a Edge node with all the client jars.
I'm able to successfully start kylin and load hive table. create a cube.
When i try to build the cube it fails at "extract fact distinct" step with below error.
I do see the "kylin_metadata" table in hbase.

java.lang.IllegalArgumentException: Failed to find metadata store by url: /home/kylin@emrad.local/apache-kylin-3.0.0-bin-hbase1x/bin/../tomcat/temp/kylin_job_meta9142223411059037619/meta
