Why is my kernel not working within Jupyter notebook?

0

I am using Jupyter notebook within Amazon EMR studio. I try to run my Jupyter notebook code and I get a kernel-related error (see attached screenshot). Also, my EMR instance is using an EC2 cluster. I am attempting to perform activities in Jupyter notebook within EMR studio while following along in the official Amazon Skills Builder course. And I am following the instructions exactly. I have tried recreating both my worskpace within studio as well as my cluster with no luck. Your help is appreciated.

The error message "HTTP 403: Forbidden" typically indicates a permissions issue or an expired session. Here are some steps you can take to troubleshoot and resolve the issue:

Follow the instructions in the error message to click "Ok" and attempt to reconnect to your Jupyter Notebook session. Sometimes, this error can occur due to a temporary glitch or network issue, and reconnecting may resolve it.

Ensure that your IAM (Identity and Access Management) user or role has the necessary permissions to access and interact with the Amazon EMR service and resources. Specifically, verify that you have permissions to create and manage EMR clusters, access EMR Studio, and perform actions within Jupyter Notebook. If the error message mentions session expiry, it's possible that your session has expired due to inactivity. Try refreshing the page or logging out and logging back in to EMR Studio to start a new session.

Review your VPC (Virtual Private Cloud) configuration, security groups, and network settings to ensure that there are no restrictions or issues preventing communication between EMR Studio and the EMR cluster.

If you continue to encounter issues, refer to the AWS documentation for Amazon EMR and EMR Studio for additional troubleshooting steps and guidance :- https://aws.amazon.com/emr/features/studio/?nc1=h_ls You can also reach out to AWS support for assistance with diagnosing and resolving the issue.

Hope it clarifies and if does I would appreciate answer to be accepted so that community can benefit for clarity, thanks ;)
