Drop table skiptrash?

["Periya.Data" <pe...@gmail.com>]

Hi,
   Is there a way to drop a table such that the contents do not go to the
.Trash dir? I have limited diskQuota in hadoop and am running large Hive
jobs in sequence. I would like to drop tables as and when they become
unnecessary and also they must not end up in .Trash..as they occupy lot of
space.

Before I begin my Hive job, I do clean out  (hadoop fs -rmr -skipTrash
...). I would like to know if there something like this to add in my hql
file.

Thanks,
PD.

option1:
set fs.trash.interval=0;

option2:
hadoop dfs -rmr --skipTrash <datapath>
drop table

Well in hive you can set hadoop variables so you can use the set command to
explicitly disable trash on the client

set x=y

If that does not work it is possible to run dfs commands from hive. Just do
your normal hadoop dfs command without specifying hadoop.

hive > dfs -rmr /user/hive/warehouse
