             Summary: Change the sort key for the schema tool validator to be <ID>
                 Key: HIVE-16974
                 URL: https://issues.apache.org/jira/browse/HIVE-16974
             Project: Hive
          Issue Type: Sub-task
          Components: HiveServer2
    Affects Versions: 3.0.0
            Reporter: Naveen Gangam
            Assignee: Naveen Gangam


In HIVE-16729, we introduced ordering of results/failures returned by schematool's validators. This allows fault injection testing to expect results that can be verified. However, they were sorted on NAME values which in the HMS schema can be NULL. So if the introduced fault has a NULL/BLANK name column value, the result could be different depending on the backend database(if they sort NULLs first or last).
So I think it is better to sort on a non-null column value.
