OK so I'm trying to use Open Source Rstudio on Azure Databricks.

I'm following the instructions here: https://learn.microsoft.com/en-us/azure/databricks/sparkr/rstudio#install-rstudio-server-open-source...

I've installed the necessary init script at "dbfs:/databricks/rstudio/rstudio-install.sh", and confirmed it exists.

However, the directions instruct me to create a cluster with the init script pointing to the above file.

When I select DBFS, I see that these scripts have been deprecated and the init script won't show up, getting this message:

"Cluster-scoped init scripts on DBFS are deprecated. They should be stored as workspace files instead."

When I select Workspace, I can add the script, but when starting the cluter I get the following error:

Init script failure:
BAD_REQUEST: requirement failed: dbfs:/databricks/rstudio/rstudio-install.sh is not absolute.

How else am I supposed to get this init script added?  Thanks
