Cloudera Connector for Tableau Installation Guide

  Note: This document only applies to connections to Impala or HiveServer1. If you have upgraded to HiveServer2, use Tableau 8.0.4 or above with the Cloudera ODBC Driver documentation available here.

The Cloudera Connector for Tableau enables your Enterprise's power users to access Hadoop data through the Business Intelligence application Tableau 7.0 (or later). The driver achieves this by translating Open Database Connectivity (ODBC) calls from Tableau into SQL and passing the SQL queries to the underlying Impala or Hive engines. The driver supports Cloudera Impala 1.0 (and later) and the Apache Hive versions supplied with CDH 4.2 and later.

Version 1.2 of the driver works with the original HiveServer and Beeswax protocols. It supports Kerberos authentication and multi-client concurrency only when connecting to Impala. This driver supports CDH3u4 (and later) with Beeswax and CDH4 (and later). This 32-bit driver is supported on Microsoft Windows Server 2008 R2 and Windows 7.

As of CDH4.1, you can deploy HiveServer2, an improved version of HiveServer that supports a new Thrift API tailored for JDBC and ODBC clients, Kerberos authentication, and multi-client concurrency.

Cloudera strongly recommends you install HiveServer2 , and use it whenever possible. (You can still use the original HiveServer when you need to, and run it concurrently with HiveServer2; see Configuring HiverServer2).

Refer the following sources for more information on Impala and Hive components:
  Important: To connect Impala to your Kerberos-secured CDH clusters, contact your Tableau account representative for an updated Tableau Data-connection Customization (TDC) file. The updated TDC file will override the Tableau connection settings to set specific parameters on the connection string that are required for a secure connection.
