Managing Access to Data Lakehouse Resources
You can manage access to the data lakehouse by assigning permissions on the Enterprise Data Catalog resources that represent Hive schemas and HDFS locations in the data lakehouse to Enterprise Data Preparation users and groups of users.
You can grant permissions to users or groups to perform the following operations on Hive schemas and HDFS locations in the data lakehouse:
- •Delete assets from the data lakehouse.
- •Download assets from the data lakehouse as comma-separated value (.csv) file or a Tableau Data Extract (.tde) files.
- •Export publications from the data lakehouse to an external database.
- •Import assets from external sources to a specific target in the data lakehouse.
- •Publish or copy prepared assets to a specific target in the data lakehouse.
- •Upload files to a specific target in the data lakehouse.
You can assign users or groups permissions to specific Hive schemas or HDFS locations represented by a resource, or to all Hive schemas or HDFS locations represented by the resource. When you grant permissions on specific schemas or locations to a user or group of users, the application displays only those schemas and locations to which a user has permissions when the user performs an import, publish, or upload operation.
