> Currently Hive supports "cluster by" which puts the columns into map-reduce 
> key.  Hadoop map-reduce actually allows different partitioning (we call 
> distribute) keys and sorting keys.
> In Hive language, we will add "distribute by" for specifying the partition 
> key, and "sort by" for specifying the sort key. "cluster by" will be a 
> short-cut for "distribute by" and "sort by" with the same keys.
