Analyze Hive Data in Infragistics Reveal

Reveal, an offering from Infragistics, serves as a data visualization tool that seamlessly integrates with CData Connect Cloud. Together, they empower users to deliver dynamic dashboards using real-time data from a diverse range of data sources, including Hive data. In this article, we will guide you through the process of connecting to Hive via Connect Cloud and subsequently linking Connect Cloud with Infragistics Reveal to construct a straightforward dashboard.

Connect to Hive from Infragistics Reveal

To work with live Hive data in Infragistics Reveal, we need to connect to Hive from Connect Cloud, provide user access to the connection, and create OData endpoints for the Hive data.

(Optional) Add a New Connect Cloud User

As needed, create Users to connect to Hive through Connect Cloud.

1. Navigate to the Users page and click Invite Users
2. Enter the new user's email address and click Send to invite the user
3. You can review and edit users from the Users page

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. Oa 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.

Connect to Hive from Connect Cloud

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

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 Hive OData Endpoints in Connect Cloud

After connecting to Hive, create OData Endpoints for the desired table(s).

1. Navigate to the OData page and click Add to create new OData endpoints
2. Select the Hive connection (e.g. ApacheHive1) and click Next
3. Select the table(s) you wish to work with and click Confirm

With the connection and OData endpoints configured, you are ready to connect to Hive data from Infragistics Reveal.

Create a Dashboard in Reveal

With Connect Cloud configured, we can visualize Hive data in Reveal.

1. Log into Reveal and click Dashboards -> New
2. Click Data Sources -> OData Feed
3. Specify the Connect Cloud OData API endpoint URL (found on the OData page): https://cloud.cdata.com/api/odata/service
4. Select Generic Credentials and
   • Set Username to a Connect Cloud username (e.g. user@mydomain.com)
   • Set Password to the PAT for the user
5. Select the entity you wish to visualize
6. Select fields and choose a chart type
