---------------------------------------

             Summary: We cannot use sortGroup on a global reduce
                 Key: FLINK-1240
                 URL: https://issues.apache.org/jira/browse/FLINK-1240
             Project: Flink
          Issue Type: Bug
            Reporter: Aljoscha Krettek


This is only an API problem, I hope.

I also know, that this is potentially a very bad idea because everything must be sorted on one node. In some cases, such as sorted first(n) this would make sense, though, since there we use a combiner.
