mount_workspace_dir notebook magic not working in EMR Studio

0

In an EMR Studio Python3 notebook, I execute the following:

%mount_workspace_dir .

And receive the following error:

UsageError: Line magic function `%mount_workspace_dir` not found.

I setup the EMR Cluster for studio using a Cloud Formation template that is accessible to Studio via Service Catalog. The Cloud Formation template specifies a bootstrap script that installs s3fs-fuse. The template also specifies a step to be executed when the cluster launches that installs emr-notebooks-magics using pip.

When the cluster launches, I execute the above %mount_workspace_dir command and receive the indicated error. I tried restarting the kernel as well using the Kernel->Restart Kernel option from the menu.

Here is the Cloud Formation template (with substitutions for subnet and bucket names):

Here is the content of the install-s3fs-fuse.sh script:

sudo amazon-linux-extras install epel -y
sudo yum install s3fs-fuse -y

I also tried with EMR 6.5.0.

Is there a step that I'm missing?
