> DISTINCT clause in aggregates is handled incorrectly by vectorized execution
> ----------------------------------------------------------------------------

> Key: HIVE-6873
> URL: https://issues.apache.org/jira/browse/HIVE-6873
> Project: Hive
> Issue Type: Bug
> Components: Query Processor
> Affects Versions: 0.13.0, 0.14.0
> Reporter: Remus Rusanu

>
> 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.
