Sergey Shelukhin commented on HIVE-5686:
----------------------------------------
I think this is the culprit:
{code}
try {
getPartExprNodeDesc(astNode, astExprNodeMap);
} catch (HiveException e) {
return;
}
{code}
When date-blah syntax is used, getPartExprNodeDesc throws exception about not
being able to convert date literal which is silently gone.
> partition column type validation doesn't quite work for dates
