HBaseTestingUtility.truncateTable介绍

[英]Truncate a table using the admin command. Effectively disables, deletes, and recreates the table. For previous behavior of issuing row deletes, see deleteTableData. Expressly does not preserve regions of existing table.
[中]使用admin命令截断表。有效地禁用、删除和重新创建表。有关以前发出行删除的行为，请参见deleteTableData。不保留现有表的区域。
