> HIVE-8875 disabled hive.optimize.sort.dynamic.partition for ACID queries.
> dynamic inserts are common in ACID and this leaves users with few options if
> they are seeing OutOfMemory errors due to too many writers.
> hive.optimize.sort.dynamic.partition sorts data by partition col/bucket
> col/sort col to ensure each reducer only needs 1 writer.
> Acid requires data in each bucket file to be sorted by ROW__ID and thus
> doesn't allow end user to determine sorting.
> So we should be able to support hive.optimize.sort.dynamic.partition with
> sort on partition col/bucket col/ROW__ID
