> 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.
