Connect Excel to Hadoop on Azure via HiveODBC

One key feature of Microsoft’s Big Data Solution is solid integration of Apache Hadoop with the Microsoft Business Intelligence (BI) components. A good example of this is the ability for Excel to connect to the Hive data warehouse framework in the Hadoop cluster. This section walks you through using Excel via the Hive ODBC driver.

Install the Hive ODBC Driver
Prerequisites:


  • Ensure that Excel 2010 64-bit is already installed before installing the HiveODBC Driver.
  • Download the 64-bit Hive ODBC driver MSI file from the Portal by clicking the Download tile after logging into HadoopOnAzure.com .
  • Note, the HiveODBC driver includes both the HiveODBC Driver and the Excel Hive-AddIn.




  1. Double click HiveODBCSetupx64.msi to start the installation.
  2. Read the license agreement.
  3. If you agree to the license agreement, click I agree and Install.

 4. Once the installation has completed, click Finish to exit the Setup Wizard.
