<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.
