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.

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.

  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.
