> Before SPARK-20946, the demo above point to the right hive metastore if the hive-site.xml is present. But now it can only point to the default in-memory one.
> Catalog is now as a variable shared across SparkSessions, it is instantiated with SparkContext's conf. After SPARK-20946, Session level configs are not pass to SparkContext's conf anymore, so the enableHiveSupport API takes no affect on the catalog instance.
> You can set spark.sql.catalogImplementation=hive application wide to solve the problem, or never create a sc before you call SparkSession.builder().enableHiveSupport().getOrCreate()
