> Key: FLINK-1599
> URL: https://issues.apache.org/jira/browse/FLINK-1599
> Project: Flink
> Issue Type: Bug
> Components: Distributed Runtime
> Affects Versions: 0.8.0
> Reporter: Maximilian Michels
> Priority: Minor
>
> If you create a custom type comparator by subclassing {{TypeComperator}} and
> implement {{int extractKeys(Object record, Object[] target, int index)}} and
> {{TypeComparator[] getFlatComparators()}} to return 0 and no type comparators
> respectively, the {{coGroup}} operator (possibly others) find matching
> elements although no comparators have been specified.
> In this case, the expected behavior for a CoGroup would be that only elements
> from one side are supplied in the CoGroup method.
