Integrate Live Impala Data into Amazon SageMaker Canvas with RDS

Amazon SageMaker Canvas is a no-code machine learning platform that lets you generate predictions, prepare data, and build models without writing code. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to Impala data for building custom machine-learning models, predicting customer churn, generating texts, building chatbots, and more. This article shows how to connect to Connect Cloud from Amazon SageMaker Canvas using the RDS connector and integrate live Impala data into your ML model deployments.

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

Configure Impala Connectivity for Amazon SageMaker Canvas

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

1. Log into Connect Cloud, click Connections, and click Add Connection.
2. Select "Impala" from the Add Connection panel.
3. Enter the necessary authentication properties to connect to Impala.

   In order to connect to Apache Impala, set the Server, Port, and ProtocolVersion. You may optionally specify a default Database. To connect using alternative methods, such as NOSASL, LDAP, or Kerberos, refer to the online Help documentation.

4. Click Create & Test.
5. Navigate to the Permissions tab in the Add Impala 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 Impala data from Amazon SageMaker Canvas.

Connecting to CData Connect Cloud from Amazon SageMaker Canvas

With the connection in CData Connect Cloud configured, you are ready to integrate live Impala data into Amazon SageMaker Canvas using its RDS connector.

1. Select a domain and user profile in Amazon SageMaker Canvas and click on "Open Canvas".
2. Once the Canvas application opens, navigate to the left panel, and select "My models".
3. Click on "Create new model" in the My models screen.
4. Specify a Model name in Create new model window and select a Problem type. Click on "Create".
5. Once the model version gets created, click on "Create dataset" in the Select dataset tab.
6. In the Create a tabular dataset window, add a "Dataset name" and click on "Create".
7. Click on the "Data Source" drop-down and search for or navigate to the RDS connector and click on " Add Connection".
8. In the Add a new RDS connection window, set the following properties:
   
   
   • Connection Name: a relevant connection name
   • Set Engine type to sqlserver-web
   • Set Port to 14333
   • Set Address as tds.cdata.com
   • Set Username to a Connect Cloud user (e.g. [email protected])
   • Set Password to the PAT for the above user
   • Set Database name the Impala connection (e.g., ApacheImpala1)
9. Click on "Create connection".

Integrating Impala Data into Amazon SageMaker Canvas

With the connection to Connect Cloud configured in the RDS, you are ready to integrate live Impala data into your Amazon SageMaker Canvas dataset.

1. In the tabular dataset created in RDS with Impala data, search for the Impala connection configured on Connect Cloud in the search bar or from the list of connections.
2. Select the table of your choice from Impala, drag and drop it into the canvas on the right.
3. You can create workflows by joining any number of tables from the Impala connection (as shown below). Click on "Create dataset".
4. Once the dataset is created, click on "Select dataset" to build your model.
5. Perform analysis, generate prediction, and deploy the model.

At this point, you have access to live Impala data in Amazon SageMaker that you can utilize to build custom ML models to generate predictive business insights and grow your organization.

SQL Access to Impala Data from Cloud Applications

Now you have a direct connection to live Impala data from Amazon SageMaker Canvas. You can create more connections, datasets, and predictive models to drive business — all without replicating Impala data.
