-------------------------------------
Summary: Remove QueryWrapper from ObjectStore
Key: HIVE-23266
URL: https://issues.apache.org/jira/browse/HIVE-23266
Project: Hive
Issue Type: Improvement
Reporter: David Mollitor
Assignee: David Mollitor
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 anyway.
Remove the {{QueryWrapper}} from the class and simplify some of the DB
interactions.
