DLT cluster : can be manipulated?

Hi All

I am using DLT pipeline to pull data from a ADLS gen2 which is mounted. The cluster that is getting fired has access mode is set to shared. I want to change it to single user. But the cluster being attached to DLT , I am not ablr to update and save.

is it non editable at all? I am getting error :[INSUFFICIENT_PERMISSIONS] Insufficient privileges: User does not have permission SELECT on any file.

how can I handle? with the same User I tried reading the file from normal notebook with All purpose cluster which has access mode: No isolation shared

Hi @kiko_roy

Greetings!

You can't use a single-user cluster to query tables from a Unity Catalog-enabled Delta Live Tables pipeline, including streaming tables and materialized views in Databricks SQL. To access these tables, you need to use a shared cluster running Databricks Runtime 13.1 or newer.

Check Below link :
