[jira] [Commented] (HIVE-5686) partition column type validation doesn't quite work for dates

    [ https://issues.apache.org/jira/browse/HIVE-5686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13815606#comment-13815606 ] 

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.
