The error message you’re encountering indicates a PermissionError related to the patch command in your local MWAA (Managed Workflows for Apache Airflow) environment. This error occurs when the DataHub plugin attempts to apply a patch using the patchy library, which internally calls the patch command.

Here are some steps you can take to resolve this issue:

  1. Check Permissions: Ensure that the user running the Airflow process has the necessary permissions to execute the patch command. This might involve checking the permissions of the patch executable and ensuring that it is accessible to the user.

  2. Install patch Command: Verify that the patch command is installed on your system. You can check this by running patch --version in your terminal. If it’s not installed, you can install it using your package manager (e.g., apt-get install patch on Debian-based systems or yum install patch on Red Hat-based systems).

  3. Modify Security Context: If you are running this in a containerized environment like OpenShift, you might need to adjust the security context to allow the execution of the patch command. This could involve modifying the securityContext in your deployment configuration to allow the necessary permissions.

  4. Review Airflow and DataHub Plugin Configuration: Ensure that your Airflow and DataHub plugin configurations are set up correctly. This includes verifying that the DataHub plugin is properly installed and configured in Airflow.

  5. Check for Environment-Specific Issues: Since you are using a local MWAA environment, there might be specific configurations or restrictions in place. Ensure that your local environment allows the execution of subprocesses and that there are no security policies preventing the use of the patch command.

If you need more detailed steps or further assistance with any of these points, please let me know!
