Databricks Notebook error: Your administrator has only allowed sql and scala commands on this cluster.

So while creating a Python notebook and running it on my Databricks Cluster I observed following error:

Your administrator has only allowed sql and scala commands on this cluster. This execution contained at least one disallowed language.

 

Its obvious that the error is due to some restriction applied at Cluster level. So I went to the Cluster settings page and checked the Spark Config and found below key-value configuration settings:

spark.databricks.repl.allowedLanguages sql,scala

 

So if you want to run other languages like Python & R you can remove the entire line or restrict any language(s) then change is as per your needs.
