Description
When using CREATE TEMPORARY TABLE with a LOCATION clause, Hive doesn't remove the created files when the session ends.
Steps to reproduce:
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"
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.
