Subject [GitHub] flink pull request: [FLINK-2861] Fields grouping on split streams ...
Date Fri, 20 Nov 2015 14:31:08 GMT
Github user StephanEwen commented on the pull request:

    I ran into that issue a while back. The problem was that you emit elements that have the
name/tag of the split stream (to use the split selector) and over that, you run the regular
    Splitting this into two steps should work: Splitting, having a mapper that removes the
"split tag" and then doing the field partitioning.
    Would be nice to make this nice in Flink, but it is tricky. Not all functions go though
a collector, and not all collectors can split.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
