Jean-Daniel Cryans commented on HBASE-7782:
-------------------------------------------

IIRC we wrote it because the disable/drop/create cycle is slow. I agree it 
could be renamed to something like deleteTableData() and have truncateTable() 
do the same as the shell.
                
> HBaseTestingUtility.truncateTable() not acting like CLI

> I would like to discuss the behavior of the truncateTable() method of 
> HBaseTestingUtility. It's currently only removing the data through a 
> scan/delete pattern.
> However, the truncate command in CLI is doing additional things: it disables 
> the tables, drop, creates (with similar column descriptors) and then enables 
> the table.
> I think the truncateTable() method is misleading; for example I used it to 
> force a coprocessor to be reloaded, but it did not. Of course I can disable 
> and enable the table by myself within my unit test, but perhaps it deserves 
> to be discussed?
