-----------------------------------

Hi [~lirui] Have you try -- SORT_BEFORE_DIFF, which is to sort the query 
result, which is different from SORT_BEFORE_DIFF. It's supposed to make query 
result sorted w/o an order by.

BTW, do you know why changing the key from BytesWrtiable to HiveKey would 
require to regenerate these test output?

> Use HiveKey instead of BytesWritable as key type of the pair RDD [Spark

> HiveKey should be used as the key type because it holds the hash code for 
> partitioning. While BytesWritable serves partitioning well for simple cases, 
> we have to use {{HiveKey.hashCode}} for more complicated ones, e.g. join, 
> bucketed table, etc.
