†Databricks Inc. *MIT CSAIL. ‡AMPLab, UC Berkeley. ABSTRACT. Spark SQL is a new module in Apache Spark that integrates rela- tional processing with Spark's functional programming API. Built on our experience with Shark, Spark SQL lets Spark program- mers leverage the benefits of relational processing (e.g.,
SparkSession in Spark 2.0 provides builtin support for Hive features including the ability to write queries using HiveQL, access to Hive UDFs, and the ability to read data from Hive tables. To use these features, you do not need to have an existing Hive setup.
