Xuefu Zhang commented on HIVE-6469:
-----------------------------------

{quote}
set hive.warehouse.data.skipTrash = true – explicitly set
drop table large10TBTable – this will skip trash
drop table anyOtherTable – this will skip trash
set hive.warehouse.data.skipTrash = false – if you forget this, it will 
skipTrash forever, until corrected.
drop table regularTable – this will start placing data in trash
{quote}
Actually I mean hive.warehouse.data.skipTrash to be an admin property that 
normal user will be able to set. Thus, the server will have this either on or 
off. I expect a prod server will have this on while a dev server will have this 
off. Isn't this good enough? Setting this on/off based on prod/dev seems more 
reasonable than on table size. If you are in a dev environment, you just 
disable the feature and why do you care whether the table is big or small. In a 
prod environment, on the other hand, everything table is important so the 
feature should be always on. Anything else I'm missing here?

> hive drop table command deletes the data from HDFS warehouse and puts it into 
> Trash.
> Currently there is no way to provide flag to tell warehouse to skip trash 
> while deleting table data.
> This ticket is to add skipTrash feature in hive command-line, that looks as 
> following. 
> hive -e "drop table skipTrash testTable"
> This would be good feature to add, so that user can specify when not to put 
> data into trash directory and thus not to fill hdfs space instead of relying 
> on trash interval and policy configuration to take care of disk filling issue.
