It also contains Catalog/Context classes to enable querying of Hive tables without having to first register them as temporary tables in Spark SQL. That's just a fact of how it works. Note: In order to use the same settings that were used in the benchmark, such as Ext4, you must make a modification to the Spark EC2 script. LLAP deals with any filtering or masking, and if the query contains requests for columns that aren't authorized, LLAP stops processing the request and throws an Authorization exception to Spark. Hive Product Management and Engineers explain Hive LLAP usage and architecture.
