Use CData Connect Cloud to create a virtual MySQL Database for HDFS data to build custom dashboards in Bold BI.

Bold BI allows you to create, share, and collaborate on interactive BI dashboards. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to HDFS data for visualizations, dashboards, and more. This article shows how to create a virtual database for HDFS and build reports from HDFS data in Bold BI.

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for HDFS, allowing you to easily build reports from live HDFS data in Bold BI — without replicating the data to a natively supported database. As you build visualizations, Bold BI generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc) directly to HDFS, leveraging server-side processing to quickly return the requested HDFS data.

Create a Virtual MySQL Database for HDFS Data

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

  1. Login to Connect Cloud 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.

With the virtual database created, you are ready to connect to HDFS data from Bold BI.

Visualize Live HDFS Data in Bold BI

The steps below outline connecting to CData Connect Cloud from Bold BI to create a new HDFS data source and build a simple visualization from the data.

  1. Log into your Bold BI instance, click the data sources tab, create a new data source, and choose the MySQL connector.
  2. Choose the basic configuration and set the connection properties:
    • Name: Name your connection
    • Server name: Your Connect Cloud instance (myinstance.cdatacloud.net)
    • Port: 3306
    • Username: Your Connect Cloud username
    • Password: Your Connect Cloud password
    • Mode: Choose Live to query HDFS on-demand or choose Extract to load the data into Bold BI
    • Database: Choose the database you created from the drop-down menu (hdfsdb)
  3. Click Connect
  4. Select the table to visualize and drag it onto the workspace.
  5. Select a visualization style and add it to the report.
  6. Click the gear icon for the visualization to configure the visualization properties and assign columns to the visualization.

SQL Access to HDFS Data from Cloud Applications

Now you have a direct, cloud-to-cloud connection to live HDFS data from your Bold BI workbook. You can create more data sources and new visualizations, build reports, and more — all without replicating HDFS data.
