> Affects Versions: 3.1.0

>
> The problem is that, for certain types of schema mismatch between the Hive
> table definition and the "hive.sql.query" parameter, Hive simply returns no
> rows rather than throwing an error when queried.
> Ideally Hive would check for schema compatibility during table definition and
> throw an error if there's a problem - the earlier the better. But even if
> that cannot be made a requirement, I'd definitely expect an error rather than
> a silent failure (i.e. zero rows returned) at runtime.
> I'm attaching investigation of this issue in "Hive-JDBC schema matching
> sensitivity.txt".
