Xuefu Zhang commented on HIVE-6469:
-----------------------------------
Here is the recap of what I have said above.
Putting data for a dropped data in the .trash folder is a safety feature. It's
understandable that in dev env user might want to turn this off. Thus, I
suggest we put a server configuration for that. This safety feature is a server
behavior, and being applied to tables does NOT mean that we need to provide an
option at table level, which appears to me an over-kill.
If the feature is desirable for production and optional for development, I
don't understand why a user would want to turn this feature on in an
environment while wanting to skip this for some tables. If instead there is
such a rare need for this, then manual deleting the data after dropping a table
seems more reasonable to me. Thus, I'm not convinced that such a requirement is
strong enough to have such a skiptrash syntax in drop table command.

> 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.
