In Power BI Desktop, you can connect to an Impala database and use the underlying data just like any other data source in Power BI Desktop. This release of the Impala connector is in Preview, and is subject to change.
To get access to the Impala connector, you first need to enable this preview feature. In Power BI Desktop, select File > Options and settings > Option then in the Options window, select the Preview Features section and enable Impala, as shown below.
When you check that box, you turn on the Impala preview feature. You'll need to restart Power BI Desktop for the change to take effect. Once you do, the preview feature is available.
Once you've enabled to preview feature, to connect to an Impala database select Get Data from the Home ribbon in Power BI Desktop. Select Database from the categories on the left, and you see Impala (Beta).
In the Impala window that appears, type or paste the name of your Impala server into the box, and select OK. Note that you can choose to Import data directly into Power BI, or you can use DirectQuery. You can learn more about using DirectQuery.
When prompted, put in your username and password, or connect anonymously - either is supported.
Note: Once you put in your username and password for a particular Impala server, Power BI Desktop uses those same credentials in subsequent connection attempts. You can modify those credentials by going to File > Options and settings > Data source settings.
Once you successfully connect, a Navigator window appears and displays the data available on the server, from which you can select one or multiple elements to import and use in Power BI Desktop.
