Debugging a Presto server project involves identifying and resolving any issues or errors in the code. Here are some steps you can take to debug a Presto server project:

1. Use logging: Include logging statements throughout your code to track the flow of execution and identify any errors or unexpected behavior. You can use logging frameworks like Log4j or SLF4J to log messages at different levels of severity.
2. Use a debugger: Set breakpoints in your code and use a debugger like IntelliJ IDEA or Eclipse to step through the code line by line, inspect variables, and track the values of different expressions. This can help you pinpoint the exact location of the issue and understand what is causing it.
3. Review error messages: Pay attention to any error messages or warnings that are displayed in the console or logs. These messages can provide valuable information about what went wrong and help you narrow down the source of the problem.
4. Check configuration files: Make sure that your configuration files are set up correctly and that all necessary properties are configured properly. Incorrect configurations can cause errors and unexpected behavior in your Presto server project.
5. Test in a controlled environment: Create a test environment where you can reproduce the issue consistently and test different scenarios. This can help you isolate the problem and find a solution without affecting the production environment.
6. Consult the Presto documentation: The Presto documentation contains valuable information about troubleshooting common issues and debugging techniques. Refer to the documentation to find relevant resources and best practices for debugging your Presto server project.

By following these steps and using the right tools, you can effectively debug your Presto server project and ensure that it runs smoothly and efficiently.
