-----------------------------------
ashutoshc has accepted the revision "HIVE-4041 [jira] Support multiple
partitionings in a single Query".
Changes look good. I will commit this once HIVE-4186 is in trunk and after I
have merged trunk into branch.

> Currently we disallow queries if the partition specifications of all Wdw fns
> are not the same. We can relax this by generating multiple PTFOps based on
> the unique partitionings in a Query. For partitionings that only differ in
> sort, we can introduce a sort step in between PTFOps, which can happen in the
> same Reduce task.
