To delete a Presto user:
- Select Security, then select Presto Users.
- In the Presto Users table, select View for the specific user.
- Select Danger Zone, then select Delete.
If the Presto user is the only user associated with a Presto cluster, that Presto user cannot be deleted.
You can delete a Presto user even if they are part of one or more active clusters. Before deleting a Presto user, be sure that user is no longer needed. You can always re-create and re-add Presto users, but this can be tedious if the Presto user is needed for a large number of clusters.
