Hello,

I recently tried running R code in a notebook. The notebook is about a year old and was used in a different cluster that no longer exists. I received the message, 'Your administrator has only allowed sql and python commands on this cluster. This execution contained at least one disallowed language.'

I thought this was curious. As it turns out it is because I am attempting to run it on a cluster configured with 'Shared' access mode, which only supports SQL and python.

My two options for configuring a cluster that supports R are 'single user' or a 'no isolation shared' access modes. Can someone provide a concise difference between the two without pointing me to documentation about the Unity Catalog. An example for each option would help.

In this case there are only two users. I don't anticipate that changing. However, I would also like to know about guidelines for different use cases, with more users, as well.

Thanks!

Peter
