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.
> Temporary table with LOCATION clause not removed after session ends

> Key: HIVE-15729
> URL: https://issues.apache.org/jira/browse/HIVE-15729
> Project: Hive
> Issue Type: Bug
> 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.
