> 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.
