With Java you can add it to a List<Delete> and delete all at once by passing the list to the table.delete(List<>) function. If you mean you're deleting a ton of volume of data, may want to use some cron job of the jar associated with this delete.
If you mean through Hbase shell, I think that only has delete a whole row or delete a single cell. I don't think it has a range-delete function unless there is a way to combine a scan and a delete.
