Alexander Kolbasov commented on HIVE-17730:
-------------------------------------------

There are also many cases where {{QueryWrapper}} isn't used and instead 
{{rollbackAndCleanup()}} is called directly to close the query. This should be 
converted to {{QueryWrapper}} as well.

> Queries can be closed automatically

> 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.
