Hello, i have a problem.

When I try to run the MLlib Assembler (from pyspark.ml.feature import VectorAssembler) I get this error and I don't know what to do anymore. Please help.

Is it High Concurrency cluster with credential passthrough enabled? In that case, you can use a different cluster mode.

https://docs.azuredatabricks.net/spark/latest/data-sources/azure/adls-passthrough.html

This exception is thrown when you have accessed a method that Azure Databricks has not explicitly marked as safe for Azure Data Lake Storage credential passthrough clusters. In most cases, the technique could allow a user on an Azure Data Lake Storage credential passthrough cluster to access another user’s credential.

Thanks you so much!

How could we whitelist this error below with DBR 13.3 and above?

I am facing the same error with Databricks Serverless (Free Edition) .... please fix it

Do you plan to support this in Serverless Free Edition? Migration from Community Edition to Serveless has been fraught with these limitations.
