CData ODBC Driver for Apache Hive

Overview

The CData ODBC Driver for Apache Hive enables real-time access to Apache Hive data, directly from any applications that support ODBC connectivity, the most widely supported interface for connecting applications with data.

The driver wraps the complexity of accessing Apache Hive data in a standard ODBC driver compliant with ODBC 3.8. Applications can then access Apache Hive as a traditional database. The driver hides the complexity of accessing data and provides additional powerful security features, smart caching, batching, socket management, and more.

Key Features

• Bidirectional access.
• Access, analyze, and report on data with your SQL-based tool of choice.
• Supports 32-bit and 64-bit applications.
• Supports the Unicode ODBC APIs and ODBC 3.8.
• Drivers for Windows, Linux, and macOS/OS X.

Getting Started

See Getting Started to create an ODBC data source name (DSN) and connect to Apache Hive from your platform.

Using the ODBC Driver/Using from Tools

See Using ODBC to connect to Apache Hive from the following programming languages and for information on the supported interfaces:

• From C/C++
• From Go
• From Node.js
• From PHP
• From Python
• From R

See Using from Tools for information on using the ODBC driver in some of the popular applications and programming languages that connect via ODBC.

See the Apache Hive integration guides for information on connecting from other applications.

Linked Server

You can use SQL Linked Server to connect to the CData SQL Gateway. SQL Server treats the CData SQL Gateway as a linked SQL Server instance, so you can write full SQL queries to query your Apache Hive data without losing performance as would happen connecting to an ODBC data source directly. The connection can be made locally or to the Gateway located on a separate machine.

See Create a Linked Server for more information.

SQL Gateway

See Connect from MySQL Workbench to configure MySQL or SQL Server entry points for Apache Hive on your server, using the included CData SQL Gateway application. The SQL Gateway listens for incoming MySQL and SQL Server connections and brokers the SQL request to the ODBC data source. This enables any MySQL or SQL Server client to connect, from PHP applications, SQL Server linked servers, and so on.

Advanced Features

Advanced Features details additional features supported by the driver, such as defining user defined views, ssl configuration, remoting, caching, firewall/proxy settings, and advanced logging.

SQL Compliance

See SQL Compliance for a syntax reference and code examples outlining the supported SQL.

Data Model

See Data Model for the available database objects. This section also provides more detailed information on querying specific Apache Hive entities.

Connection Properties

The Connection properties describe the various options that can be used to establish a connection.
