Spark SQL Query data with Java String query = "SELECT * FROM table"; ResultSet results = session.execute (query); At the core of Spark SQL there is what is called a DataFrame. A DataFrame simply holds data as a collection of rows and each column in the row is named. With DataFrame s you can easily select, plot, and filter data.
