------------------------------
Hi Xuefu,
This feature typically required to be used on ad-hoc basis rather than globally
applied to all drop operation.
2 of our primary customers specifically has asked for this feature. they want
to use this for dev environment users where they can specifically mention
to skip trash, but not for production environment users.
Also some people may find this useful

> 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.
