EMR Serverless + Link Git Repository

Question

The documentation explains how to add a Git Repository but doesn't go into any details on whether or not this is supported with EMR Serverless. I've tried, unsuccessfully, to add in a Git Repository with using EMR Serverless -- I end up with an "Internal Error" when performing the linking step. I've verified that the Studio can get out to the internet (with just a simple urllib.request) plus I've made sure the permissions are correct (I've went so far as to temporarily add Admin to the roles to make sure there wasn't some missing permission) My security groups seem to be setup correctly.

Has anybody actually used linking a git repo to an EMR Serverless Studio? Is there some step missing in the instructions?

Based on the available information, it appears that linking a Git repository directly to EMR Serverless is not a supported feature. The documentation and instructions for linking Git repositories to EMR Studios are primarily focused on EMR on EC2 clusters and EMR Studio Workspaces, not EMR Serverless.

EMR Serverless is designed with a different architecture compared to traditional EMR clusters. In EMR Serverless, there is no concept of a "master node" or specific cluster nodes, as everything is abstracted away. This fundamental difference in architecture may be the reason why Git repository linking is not directly supported in EMR Serverless.

The "Internal Error" you're encountering when trying to link a Git repository to EMR Serverless is likely due to this lack of support rather than a permissions or network configuration issue.

For EMR Serverless, you might need to consider alternative approaches to integrate with Git repositories. This could involve:

1. Using Git commands or tools within your Spark jobs or notebooks to clone or pull from repositories as needed.
2. Incorporating Git operations into your job submission process, rather than trying to link repositories directly to the EMR Serverless environment.
3. Using other AWS services like AWS CodeCommit or AWS CodePipeline to manage your source code and integrate it with your EMR Serverless workflows.

If Git integration is crucial for your workflow, you might want to consider using EMR on EC2 with EMR Studio Workspaces instead of EMR Serverless, as these environments have documented support for Git repository linking.

It's worth noting that EMR Serverless is a relatively new service, and features are continually being added. You may want to check the latest AWS documentation or reach out to AWS support for the most up-to-date information on Git integration capabilities with EMR Serverless.
