Jesus Camacho Rodriguez commented on HIVE-13068:
------------------------------------------------

[~ashutoshc], I have done another pass through the new q test files. I have created follow-up
JIRA cases for all the issues discussed in RB. I will upload a new patch shortly with the
regenerated q files after the new updates to the patch. Let's try to get it in, and then I'll
continue with the rest. Thanks

> After HIVE-12543 went in, we need follow-up work to disable the last call to ConstantPropagate
in Hive. This probably implies work on extending the constant folding logic in Calcite.
