I am a beginner. I installed Apache Kylin on EMR per instructions on the
kylin website and am at my first step in the tutorials which is building the
sample kylin_sales cube.
When I try to build I keep getting this error and the second step
"Redistribute Flat Hive Table":
MetaException(message:Could not connect to meta store using any of the URIs
