[jira] [Created] (HIVE-20944) Not validate stats during query compilation

Daniel Dai created HIVE-20944:
---------------------------------

             Summary: Not validate stats during query compilation 
                 Key: HIVE-20944
                 URL: https://issues.apache.org/jira/browse/HIVE-20944
             Project: Hive
          Issue Type: Bug
            Reporter: Daniel Dai
            Assignee: Daniel Dai


In a discussion with [~ashutoshc], we find currently query planning only use valid stats. If the stats are outdated, Hive will not get any stats. Hive shall use whatever we can find in metastore. It does not need to be up to date during query planning.
