I encountered an error when trying to use dbutils to operate on files with a file: prefix.

[liu]

When I execute the statement:

dbutils.fs.ls("file:/tmp/")

I receive the following error:

ExecutionError: (java.lang.SecurityException) Cannot use com.databricks.backend.daemon.driver.WorkspaceLocalFileSystem - local filesystem access is forbidden

Does anyone know the cause of this?  help  help

Hi @liu ,

Which type of cluster are you using? Which access mode? Your compute must have Dedicated (formerly single user) access mode

[liu]

thank you very much

I created a dedicated compute instance, and I’m now able to access local files.

Can I ask one more question? When creating a compute instance, what options should I pay attention to?
