> The vectorized aggregates ignore the DISTINCT clause. This cause incorrect 
> results. Due to how GroupByOperatorDesc adds the DISTINCT keys to the overall 
> aggregate keys the vectorized aggregates do account for the extra key, but 
> they do not process the data correctly for the key. the reduce side the 
> aggregates the input from the vectorized map side to results that are only 
> sometimes correct but mostly incorrect. HIVE-4607 tracks the proper fix, but 
> meantime I'm filing a bug to disable vectorized execution if DISTINCT is 
> present. Fix is trivial.
