Cloudera JDBC Driver for Apache Hive Files

Installing and Using the Cloudera JDBC Driver for Apache Hive

To install the Cloudera JDBC Driver for Apache Hive on your machine, extract the files from the

appropriate ZIP archive to the directory of your choice.

To access a Hive data store using the Cloudera JDBC Driver for Apache Hive, you need to configure

the following:

l The list of driver library files (see "Referencing the JDBC Driver Libraries" on page 8) l The Driver or DataSource class (see "Registering the Driver Class" on page 9) l The connection URL for the driver (see "Building the Connection URL" on page 10)

Referencing the JDBC Driver Libraries

Before you use the Cloudera JDBC Driver for Apache Hive, the JDBC application or Java code that

you are using to connect to your data must be able to access the driver JAR files. In the application

or code, specify all the JAR files that you extracted from the ZIP archive.

Using the Driver in a JDBC Application

Most JDBC applications provide a set of configuration options for adding a list of driver library

files. Use the provided options to include all the JAR files from the ZIP archive as part of the driver

configuration in the application. For more information, see the documentation for your JDBC

application.

Using the Driver in Java Code

You must include all the driver library files in the class path. This is the path that the Java Runtime

Environment searches for classes and other resource files. For more information, see "Setting the

Class Path" in the appropriate Java SE Documentation.

Registering the Driver Class

Before connecting to your data, you must register the appropriate class for your application.

The following classes are used to connect the Cloudera JDBC Driver for Apache Hive to Hive data

stores: l The Driver classes extend java.sql.Driver. l The DataSource classes extend javax.sql.DataSource and

javax.sql.ConnectionPoolDataSource.

The driver supports the following fully-qualified class names (FQCNs) that are independent of the

JDBC version:

l com.cloudera.hive.jdbc.HS1Driver

l com.cloudera.hive.jdbc.HS2Driver

l com.cloudera.hive.jdbc.HS1DataSource

l com.cloudera.hive.jdbc.HS2DataSource
