DROP USER removes an existing user. In Cassandra 2.0.9 and later, you can test that the user exists. Attempting to drop a user that does not exist results in an invalid query condition unless the IF EXISTS option is used. If the option is used, the statement will be a no-op if the user does not exist. You have to be logged in as a superuser to issue a DROP USER statement. A user cannot drop themselves.
Enclose the user name in single quotation marks only if it contains non-alphanumeric characters.
