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:
