    Description

      The following query:

      INSERT OVERWRITE TABLE t SELECT 1 WHERE FALSE

      should serve to truncate a table by producing an empty base data directory. In fact no new base directory is created, so the table is not cleared. (at least with an insert_only table, I didn't test full-ACID)

      This bug does not seem to happen with non-transactional tables.
