Connect Excel to Apache Hadoop by using Power Query

  • Alt

One key feature of the Microsoft big-data solution is the integration of Microsoft business intelligence (BI) components with Apache Hadoop clusters in Azure HDInsight. A primary example is the ability to connect Excel to the Azure Storage account that contains the data associated with your Hadoop cluster by using the Microsoft Power Query for Excel add-in. This article walks you through how to set up and use Power Query to query data associated with a Hadoop cluster managed with HDInsight.

Prerequisites

  • An Apache Hadoop cluster on HDInsight. See Get Started with HDInsight on Linux.
  • A workstation that is running Windows 10, 7, Windows Server 2008 R2, or a later operating system.
  • Microsoft 365 apps for enterprise, Office 2016, Office 2013 Professional Plus, Excel 2013 Standalone, or Office 2010 Professional Plus.

Install Microsoft Power Query

Power Query can import data that has been output or that has been generated by a Hadoop job running on an HDInsight cluster.

In Excel 2016, Power Query has been integrated into the Data ribbon under the Get & Transform section. For older Excel versions, download Microsoft Power Query for Excel from the Microsoft Download Center and install it.

Import HDInsight data into Excel

The Power Query add-in for Excel makes it easy to import data from your HDInsight cluster into Excel, where BI tools such as PowerPivot and Power Map can be used to inspect, analyze, and present the data.

  1. Launch Excel.

  2. Create a new blank workbook.

  3. Perform the following steps based on the Excel version:

    • Excel 2016

      • Select > Data > Get Data > From Azure > From Azure HDInsight(HDFS).

        HDI.PowerQuery.SelectHdiSource.2016.

    • Excel 2013/2010

      • Select Power Query > From Azure > From Microsoft Azure HDInsight.

        HDI.PowerQuery.SelectHdiSource.

        Note: If you don't see the Power Query menu, go to File > Options > Add-ins, and select COM Add-ins from the drop-down Manage box at the bottom of the page. Select the Go... button and verify that the box for the Power Query for Excel add-in has been checked.

        Note: Power Query also allows you to import data from HDFS by selecting From Other Sources.

  4. From the Azure HDInsight(HDFS) dialog, in the Account name or URL text box, enter the name of the Azure Blob storage account associated with your cluster. Then select OK. This account can be the default storage account or a linked storage account. The format is https://StorageAccountName.blob.core.windows.net/.

  5. For Account Key, enter the key for the Blob storage account, and then select Connect. (You need to enter the account information only the first time you access this store.)

  6. In the Navigator pane on the left of the Query Editor, double-click the Blob storage container name associated with your cluster. By default, the container name is the same name as the cluster name.

  7. Locate HiveSampleData.txt in the Name column (the folder path is ../hive/warehouse/hivesampletable/), and then select Binary on the left of HiveSampleData.txt. HiveSampleData.txt comes with all the cluster. Optionally, you can use your own file.

    HDI Excel power query import data.

  8. If you want, you can rename the column names. When you're ready, select Close & Load. The data has been loaded to your workbook:
