Description

In HiveMetaStore.java drop_database_core function, HIVE-11258 updates the startIndex from endIndex incorrectly inside if (tables != null && !tables.isEmpty()) statement. If the tables get deleted before getTableObjectsByName() call, then returned table list is empty and startIndex won't get updated.
