Connect to Athena Data in IntelliJ

Integrate connectivity to Athena data with wizards in IntelliJ.

The CData JDBC Driver for Athena enables you to access Athena as a JDBC data source, providing integration with rapid development tools in IDEs. This article shows how to use the data source configuration wizard to connect to Athena data in IntelliJ.

Create a JBDC Data Source for Athena

Follow the steps below to add the driver JAR and define connection properties required to connect to Athena data.

  1. In the Data Sources window, right-click and then click Add Data Source -> DB Data Source.
  2. In the Data Source Properties dialog that appears, the following properties are required:

    • JDBC Driver Files: Click the button next to this menu to add the JDBC Driver file cdata.jdbc.amazonathena.jar, located in the installation directory.
    • JDBC Driver Class: In this menu, select cdata.jdbc.amazonathena.AmazonAthenaDriver from the list.
    • Database URL: Enter the connection URL in the JDBC URL property. The URL must start with jdbc:amazonathena: and includes connection properties separated with semicolons.

      Authenticating to Amazon Athena

      To authorize Amazon Athena requests, provide the credentials for an administrator account or for an IAM user with custom permissions: Set AccessKey to the access key Id. Set SecretKey to the secret access key.

      Note: Though you can connect as the AWS account administrator, it is recommended to use IAM user credentials to access AWS services.

      Obtaining the Access Key

      To obtain the credentials for an IAM user, follow the steps below:

      1. Sign into the IAM console.
      2. In the navigation pane, select Users.
      3. To create or manage the access keys for a user, select the user and then select the Security Credentials tab.

      To obtain the credentials for your AWS root account, follow the steps below:

      1. Sign into the AWS Management console with the credentials for your root account.
      2. Select your account name or number and select My Security Credentials in the menu that is displayed.
      3. Click Continue to Security Credentials and expand the Access Keys section to manage or create root account access keys.

      Authenticating from an EC2 Instance

      If you are using the CData Data Provider for Amazon Athena 2018 from an EC2 Instance and have an IAM Role assigned to the instance, you can use the IAM Role to authenticate. To do so, set UseEC2Roles to true and leave AccessKey and SecretKey empty. The CData Data Provider for Amazon Athena 2018 will automatically obtain your IAM Role credentials and authenticate with them.

      Authenticating as an AWS Role

      In many situations it may be preferable to use an IAM role for authentication instead of the direct security credentials of an AWS root user. An AWS role may be used instead by specifying the RoleARN. This will cause the CData Data Provider for Amazon Athena 2018 to attempt to retrieve credentials for the specified role. If you are connecting to AWS (instead of already being connected such as on an EC2 instance), you must additionally specify the AccessKey and SecretKey of an IAM user to assume the role for. Roles may not be used when specifying the AccessKey and SecretKey of an AWS root user.

      Authenticating with MFA

      For users and roles that require Multi-factor Authentication, specify the MFASerialNumber and MFAToken connection properties. This will cause the CData Data Provider for Amazon Athena 2018 to submit the MFA credentials in a request to retrieve temporary authentication credentials. Note that the duration of the temporary credentials may be controlled via the TemporaryTokenDuration (default 3600 seconds).

      Connecting to Amazon Athena

      In addition to the AccessKey and SecretKey properties, specify Database, S3StagingDirectory and Region. Set Region to the region where your Amazon Athena data is hosted. Set S3StagingDirectory to a folder in S3 where you would like to store the results of queries.

      If Database is not set in the connection, the data provider connects to the default database set in Amazon Athena.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the Athena JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.amazonathena.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      A typical JDBC URL is the following:

      jdbc:amazonathena:AccessKey='a123';SecretKey='s123';Region='IRELAND';Database='sampledb';S3StagingDirectory='s3://bucket/staging/';

Edit and Save Athena Data

To discover schema information, right-click the data source you just created and click Refresh Tables. To query a table, right-click it and then click Open Tables Editor. You can also modify records in the Table Editor.
