Subject [GitHub] incubator-flink pull request: [FLINK-658] Group Sorting for CoGrou...

Github user StephanEwen commented on the pull request:

    @aljoscha  Can you have a look at this?
    The code fails when using the "default co group" in the Scala API (see ignored test https://github.com/apache/incubator-flink/pull/234/files#diff-4f9cfc3e3b499122f9e12653b5761e1aR124)
    The reason is the current way of wrapping the Operators in a Scala Data Set, together
with the shared binary key operations (that prevent operator specific functions, like group
sorting). I am not sure what would be the best way to solve this without quite some changes
to the Scala APIs design.
