getting error while creating mount point in data bricks

Question

Hi,

I am getting the following error when trying to create mount point.

py4j.security.Py4JSecurityException: Method public com.databricks.backend.daemon.dbutils.DBUtilsCore$Result com.databricks.backend.daemon.dbutils.DBUtilsCore.mount(java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.util.Map) is not whitelisted on class class com.databricks.backend.daemon.dbutils.DBUtilsCore

Hi @Lakshmi Narayana Sarma Bhamidipati

Greetings & Welcome to Microsoft Q&A forum! Thanks for posting your query!

The error you are facing is because, when utilizing a High Concurrency cluster and enabling credential pass through, this problem occurs with various library operations. When you visit a method that Azure Databricks hasn't expressly designated as safe for Azure Data Lake Storage credential passthrough clusters, this issue is raised.

For more details, please refer: https://learn.microsoft.com/en-us/azure/databricks/archive/credential-passthrough/adls-passthrough#passthrough-troubleshooting

Below are the workarounds that you may consider for resolving your query.

• Use a different cluster mode as a workaround if it describes your situation.
• Update spark.databricks.pyspark.enableProcessIsolation to false for this your cluster needs to be with no isolation shared access mode
• Update spark.databricks.pyspark.enablePy4JSecurity to false
• Use standard clusters in your case as a workaround.

Hope this helps. Do let us know if you have any further queries.
