Subject [jira] [Commented] (HIVE-6469) skipTrash option in hive command line
Date Thu, 24 Apr 2014 06:47:15 GMT

Ashutosh Chauhan commented on HIVE-6469:
----------------------------------------

I agree with [~xuefuz] in principle. We should be extremely careful about what are we adding
in language. skipTrash does sound like too-specific extension which is exposing underlying
implementation detail. We should explore alternatives to accomplish desired functionality,
even if it turns out to be slightly inconvenient.

> 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.
