[jira] [Created] (PHOENIX-3689) Not determinist order by with limit

Arthur created PHOENIX-3689:
-------------------------------

             Summary: Not determinist order by with limit
                 Key: PHOENIX-3689
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3689
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.7.0
            Reporter: Arthur


The following request does not return the last value of myTable:
select * from myTable order by myKey desc limit 1;
Adding a 'group by myKey' clause gets back the good result.

I noticed that an order by with 'limit 10' returns a merge of 10 results from each region and not 10 results of the whole request.

So 'order by' is not determinist. It is a bug or a feature ?
