If you have the role of User, Power User, or Administrator, you can delete any data set from the Catalog. If you have the role of Viewer, you cannot delete a data set.
You cannot delete a data set that is currently being used in a project.
To delete a data set, click Delete on the data set details panel.
Note:
Deleting a data set from the Catalog does not delete its corresponding Hive table in the Hive database. For details about the relationship between a data set and its Hive table, see the Data Processing Guide.
