Subject [jira] [Commented] (HIVE-15729) Temporary table with LOCATION clause not removed after session ends
Date Thu, 26 Jan 2017 00:29:26 GMT

Gopal V commented on HIVE-15729:
--------------------------------

I think this is not a direct result of the temporary table implementation - the temporary
tables are deleted when the session dir gets wiped out.

>             Project: Hive

>            Reporter: Marcus T
>            Priority: Minor

> When using CREATE TEMPORARY TABLE with a LOCATION clause, Hive doesn't remove the created
files when the session ends.
> Steps to reproduce:
> {noformat}
> beeline
>   CREATE TEMPORARY TABLE this_gets_removed AS SELECT 'OK';
>   CREATE TEMPORARY TABLE this_stays LOCATION '/tmp/this_stays' AS SELECT 'BAD';
>   !quit
> hdfs dfs -ls -R "/tmp/hive/${USER}" "/tmp/this_stays"
> {noformat}
> Expected result: files and directories for {{this_gets_removed}} and {{this_stays}} are
removed.
> Actual result: files and directories for {{this_gets_removed}} are removed, files and
directories for {{this_stays}} are still present.
> Ideally, it would be great if the LOCATION clause worked with the TEMPORARY clause. 
If they can't be made to work together, perhaps the LOCATION clause should be illegal when
using TEMPORARY.
