Hi guys，
I installed kylin2.0 on a CDH cluster which also have other kylin instances.
When I start to build sample cube，I find such error in logs in ‘Redistribute
Flat Hive Table’step. Have you ever met such errors?
Caused by: ERROR XJ040: Failed to start database
'/var/lib/hive/metastore/metastore_db' with class loader
