Subject [jira] [Commented] (HIVE-6469) skipTrash option in hive command line
Date Tue, 22 Apr 2014 04:40:16 GMT


Xuefu Zhang commented on HIVE-6469:

set = true – explicitly set
drop table large10TBTable – this will skip trash
drop table anyOtherTable – this will skip trash
set = false – if you forget this, it will skipTrash forever,
until corrected.
drop table regularTable – this will start placing data in trash
Actually I mean 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.
