First query works. Added test case in the patch and verified results against 
pg. Second doesn't because of multiple sort columns without a window frame 
restriction. Though a close variant of that does work. Added it as testcase.

 I am not sure if this is illegal query. I tried following two queries in 
 postgres, both of them succeeded.
 select p_mfgr, avg(p_retailprice) over(partition by p_mfgr, p_type order by 
 p_mfgr) from part;
 select p_mfgr, avg(p_retailprice) over(partition by p_mfgr order by 
 p_type,p_mfgr) from part;

 The first one doesn't make sense, right? Order on a subset of the partition 
 columns
 The second one: Can we do this with the Hive ReduceOp have the orderColumns 
 be in a different order than the key columns?
