----------------------------------------
[~jdere] Would you like to re-upload the patch and mark patch available on this
so that we can get HIVE QA run on this? Else, if you have already ran tests on
this patch, can you post the result here.
> Change type compatibility methods to use PrimitiveCategory rather than
> TypeInfo

>
> The type compatibility methods in the FunctionRegistry (getCommonClass,
> implicitConvertable) compare TypeInfo objects directly when its doing its
> type compatibility logic. This won't work as well with qualified types
> (varchar, char, decimal), because we will need different TypeInfo objects to
> represent varchar(5) and varchar(10), and the equality comparisons won't work
> anymore. We can change this logic to look at the PrimitiveCategory for the
> TypeInfo instead.
> NO PRECOMMIT TESTS - dependent on changes in HIVE-5203
