Subject [jira] [Commented] (FLINK-940) DeltaIteration coGroup at SolutionSet doesn't find values
Date Tue, 17 Jun 2014 15:25:38 GMT

    [ https://issues.apache.org/jira/browse/FLINK-940?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14033920#comment-14033920

Stephan Ewen commented on FLINK-940:

Can you attach the code of the program with that problem?

I have written a program that uses a co group with the solution set, taking the solution set
as the second input, and it works fine.

> If I execute a coGroup on a SolutionSet, the grouping doesn't find any matching tuples,
but if I reverse the grouping(SolutionSet as second set), matching tuples are found.
