Step 1 - Download the Simba JDBC Driver from the DataStax Drivers Download page and unpack it on the machine where R is installed. Step 2 - Add SparkJDBC41.jar and the rest of the JAR files (from step 1) to the classpath. Step 3 - Add the JDBC driver class com.simba.spark.jdbc41.Driver. From the Jackson download page, download the core-asl and mapper-asl jars. Add avro-1.8.1.jar and the Jackson jars to your project's classpath (avro-tools will be used for code generation). Alternatively, if you are using Maven, add the following dependency to your POM:
The Hive package must be copied to ./libs/cloudera/hive/ and the Impala package to ./libs/cloudera/impala. Each download packages has several JDBC driver zip files. Ensure that you use the JDBC4 (not JDBC41) zip file for the compatible drivers. For both, Impala and Hive, JDBC4 drivers are the only supported version.

Saiku - Business Analytics. Saiku allows business users to explore complex data sources, using a familiar drag and drop interface and easy to understand business terminology, all within a browser. DataSketches is an open source, high-performance library of stochastic streaming algorithms commonly called "sketches" in the data sciences. Sketches are small, stateful programs that process massive data as a stream and can provide approximate answers, with mathematical guarantees, to computationally difficult queries orders-of-magnitude faster than traditional, exact methods.
