    Description

      HIVE-16213 made QueryWrapper AutoCloseable, but queries are still closed manually and not by using try-with-resource. And now Query itself is auto closeable, so we don't need the wrapper at all.

      So we should get rid of QueryWrapper and use try-with-resource to create queries.
