How to integrate Metabase with Hive Data

Metabase is an open source data visualization tool that allows users to create interactive dashboards. When paired with CData Connect Cloud, users can easily create visualizations and dashboards linked to live Hive data. This article describes how to connect to Hive and build a simple visualization using Hive data.

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

Configure Hive Connectivity for Metabase

Connectivity to Hive from Metabase is made possible through CData Connect Cloud. To work with Hive data from Metabase, we start by creating and configuring a Hive connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Hive" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Hive. Set the Server, Port, TransportMode, and AuthScheme connection properties to connect to Hive.
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Hive Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to Hive data from Metabase.

Connect to CData Connect from Metabase

After creating the virtual database, navigate to your Metabase instance. Use the SQL Server interface to connect to Connect Cloud.

1. Navigate to the administration screen (Settings -> Admin) and click "Add Database" from the "Databases" tab
2. Configure the connection to Connect Cloud and click "Save"
   • Database type: Select "SQL Server"
   • Name: Name the connection (e.g. "Hive (Connect Cloud)")
   • Host: tds.cdata.com
   • Port: 14333
   • Database name: The name of the connection you just created (e.g. ApacheHive1)
   • Username: A Connect Cloud username (e.g. [email protected])
   • Password: The PAT for the above Connect Cloud user
   • Click to Use a secure connection (SSL)

Execute Hive Data with Metabase

Once you configure the connection to Connect Cloud, you can query Hive and build visualizations.

1. Use the "Write SQL" tool to retrieve the Hive data
2. Write a SQL query based on the Hive connection in CData Connect Cloud, e.g.
   
   

   SELECT City, CompanyName FROM Customers

3. Navigate to the "Visualization" screen, choose a visualization, and configure the visualization
