Hi @Vibhakar Prasad​, This error message suggests you are encountering a Py4JSecurityException when trying to mount a file system in Databricks.

Py4J is the Java gateway library used by Databricks to enable communication between Python and Java code.

The error occurs when the mounting method in the DBUtilsCore class is not whitelisted for security reasons.

By default, only a limited set of methods are whitelisted to prevent potentially unsafe operations.

@Kaniz Fatma​ I am also facing the same exception when I am trying to mount Gen1 datalake store on azure databricks through python.

I get that by default, only a limited set of methods are whitelisted to prevent potentially unsafe operations, but how do I whitelist this method and get the mount working without the error?
