David Mollitor commented on HIVE-23266:
---------------------------------------
Good catch on the RuntimeException. I've updated the PR to make this a bit
cleaner. The problem was rooted in the fact that {{convertToParts}} throws a
{{MetaException}} but {{listMPartitionsWithProjection}} throws a plain old
{{Exception}}.

> There is currently a utility called {{QueryWrapper}} that makes a normal
> {{Query}} auto-closable. However, {{Query}} is now in fact already
> auto-closing, so there is no need for this class. In trying to remove it, I
> realized that this wrapper was being passed around in pretty convoluted ways
> and also it was sometimes being created in a {{try-with-resources}} block but
> then never actually used in any way.
> Remove the {{QueryWrapper}} from the class and simplify some of the DB
> interactions.
