Resolving AWS Glue JDBC Connection Issues: Common Pitfalls and Solutions

Creating a JDBC connection in AWS Glue using the AWS Cloud Development Kit (CDK) can sometimes lead to unexpected issues, particularly when it comes to validation in the AWS console. If you've encountered a situation where your JDBC connection seems invalid until you manually enter the password, you're not alone. In this post, we'll explore the problem and provide a step-by-step guide on how to fix it.

The Problem

When setting up a JDBC connection in AWS Glue using CDK, it's common to leverage AWS Secrets Manager to manage sensitive information like database usernames and passwords. In some cases, developers notice that while the username is correctly retrieved from the secret, the connection still requires manual intervention in the AWS console to enter the password before it becomes valid. This raises the question: is there something wrong with your approach?

Key Observations:

The username is correctly read from Secrets Manager.

Manual entry of the password in the console is required to validate the connection.

Understanding the Solution

After troubleshooting this issue, it was discovered that certain crucial properties were missing in the connection setup. Here’s how to resolve this issue effectively:

1. Missing Properties

The root cause of the problem often lies in the absence of essential parameters in the ConnectionProperties and PhysicalConnectionRequirements. The following parameters need to be checked and added if they’re absent:

ConnectionProperties:

JDBC_ENFORCE_SSL: This property determines whether SSL is enforced for your JDBC connection.

PhysicalConnectionRequirements:

AvailabilityZone: This is required to specify the availability zone for your resources.

2. Using AWS CLI to Verify Connection Details

A practical method for reviewing existing connections is using the AWS CLI. By fetching the details of previously successful connections, you can identify missing properties in your connection setup. Here’s how you can do it:

3. Updating Your CDK Code

Once you identify the missing parameters, incorporate them into your existing CDK code. Below is a revised version of the previous code snippet that includes the required properties:

Conclusion

By ensuring that you include the necessary parameters like JDBC_ENFORCE_SSL in your ConnectionProperties and specifying the AvailabilityZone in your PhysicalConnectionRequirements, your JDBC connections in AWS Glue should work seamlessly without requiring manual password entry in the console. This structured approach can help prevent similar pitfalls when configuring AWS services using CDK.

With these insights, you'll be better equipped to handle your AWS Glue JDBC connections effectively. Happy coding!
