 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;
 {noformat}

 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?

[~rhbutani] Yeah.. I wasn't sure either about legality of such queries. Thats 
why I tried it on postgres. Amazingly, they succeeded on postgres. Need to dig 
more into it.
