I used to be able to list the mount points but I get this error now.

%python
display(dbutils.fs.mounts())

py4j.security.Py4JSecurityException: Method public com.databricks.backend.daemon.dbutils.DBUtilsCore$Result com.databricks.backend.daemon.dbutils.DBUtilsCore.mounts() is not whitelisted on class class com.databricks.backend.daemon.dbutils.DBUtilsCore

Have you tried suggested on my previous MS Q&A thread: https://learn.microsoft.com/en-us/answers/questions/827502/not-able-to-mount-on-adls-gen2-when-using-a-high-c

I tried to display the execpted outpout with Azure Databricks runtime version: 13.3 LTS.

Answer 2

Hello,

As suggested on this thread:

Below are the three workarounds to resolve this issue:

• Update spark.databricks.pyspark.enableProcessIsolation to false
• Update spark.databricks.pyspark.enablePy4JSecurity to false
• Use standard clusters.

I would recommend using a standard cluster, but those are the current workarounds that should allow you to move forward.

If this is helpful please accept answer.
