About this document
Spark SQL: DataFrames and Hive Integration by ArXlan Xahir is a document available to read on EtoBox.
1) Spark SQL allows querying Spark DataFrames using SQL and makes DataFrames and database tables interoperable. 2) A Yelp dataset is loaded as a DataFrame and registered as a temporary SQL table to run SQL queries on it, including filtering, aggregation, and joins. 3) DataFrames can be saved permanently to Hive tables for persistence across Spark sessions.
