Hive: Ist es möglich, benennen Sie eine bestehende hive-Datenbank?

Scheint es eine ähnliche Anforderung: https://issues.apache.org/jira/browse/HIVE-4847

Jedoch, als ich versuchte, die vorgeschlagenen syntax aus dem Ausgabe-Beschreibung - 'ALTER DATABASE < dbname > "UMBENENNEN", UM newdbname', es gab mir die folgende Fehlermeldung:

ALTER DATABASE testdb RENAME TO testdb1;
