Integrate Live HDFS Data into Custom Business Apps Built in Power Apps

Use the CData Cloud Hub to create a virtual SQL Server Database for HDFS data and integrate live HDFS data into apps built in Microsoft Power Apps.

Power Apps is a service for building and using custom business apps that connect to your data and work across the web and mobile — without the time and expense of custom software development. When paired with the CData Cloud Hub, you get instant, cloud-to-cloud access to HDFS data from the apps you build using Power Apps. This article shows how to connect the Cloud Hub from Power Apps and build an app based on live HDFS data.

The CData Cloud Hub provides a pure SQL, cloud-to-cloud interface for HDFS, allowing you to easily integrate with live HDFS data in Power Apps — without replicating the data. The CData Cloud Hub looks exactly like a SQL Server database to Power Apps and uses optimized data processing out of the box to push all supported SQL operations (filters, JOINs, etc) directly to HDFS, leveraging server-side processing to quickly return HDFS data.

Create a Virtual SQL Database for HDFS Data

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "HDFS" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to HDFS.

    In order to authenticate, set the following connection properties:

    • Host: Set this value to the host of your HDFS installation.
    • Port: Set this value to the port of your HDFS installation. Default port: 50070
  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

Connecting to the CData Cloud Hub

To use the Cloud Hub to integrate HDFS data into your Power Apps, you need a new SQL Server connection:

  1. Log in to Power Apps
  2. Click Data -> Connections -> New connection
  3. Select SQL Server
  4. In the connection wizard:

    • Choose to connect directly
    • Set SQL server name to the address of your Cloud Hub instance (myinstance.cdatacloud.net)
    • Set SQL database name to the name of the virtual HDFS database you created earlier (like hdfsdb)
    • Set the Username and Password and click Create

Building a Data-Centric App for HDFS Data

With the connection to the Cloud Hub configured, you are ready to integrate live HDFS data into the apps you build in Power Apps.

  1. Log in to Power Apps
  2. Click Create, hover over "Start from data" and click Make this app
  3. Select the SQL Server connection you created
  4. Search for or choose a table to work with
  5. Click Connect
  6. Customize the newly created app just like you would any other, including changing the layout and setting the fields exposed in BrowseScreen, DetailScreen, and EditScreen

At this point, you have an app with read access to live HDFS data that you can save and publish for use within your organization.

SQL Access to HDFS Data from Cloud Applications

Now you have a direct connection to live HDFS data from Microsoft Power Apps. You can create more connections and apps to drive business — all without replicating HDFS data.
