Ravi Prakash commented on HIVE-6469:
------------------------------------
There may be multiple users in each of those environments. So unless we have an
isolated "environment" for each user (which is really unmanageable) the global
settings for one user will affect other users using the same environment. What
you are suggesting is much coarser granularity and would be ops nightmare if I
am understanding your solution.
The use case that is being targeted here is that a user may on *1* instance
choose to drop a (possibly big) table without sending it to Trash to avoid
filling up her/his quota. We believe that the default Hive behavior of sending
to Trash should be maintained (to prevent accidental data loss).
It might be worthwhile to be consistent with underlying Hadoop philosophy where
users wanting to get rid of data (via 'hdfs dfs -rm') can choose whether or not
to permanently remove that data (with a '-skipTrash') option. You could make
all the same arguments about individual users caring/not caring about
controlling this behavior for that case too.
Do you see any of your customers asking for the global config rather than
on-demand flag? Perhaps that can be a separate JIRA?

> 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.
