> Wrong Generic for setKeyGroupingComparator/setKeyOrderComparator in
> MultipleInputsMapReduceDriverBase
> -----------------------------------------------------------------------------------------------------

> Key: MRUNIT-221
> URL: https://issues.apache.org/jira/browse/MRUNIT-221
> Project: MRUnit
> Issue Type: Bug
> Affects Versions: 1.1.0
> Reporter: Mathias Rüdiger
> Attachments: MRUNIT-221.patch

>
> {{setKeyGroupingComparator(final RawComparator<K2> groupingComparator)}} and
> {{setKeyOrderComparator(final RawComparator<K2> orderComparator)}} are both
> using the {{K2}} generic which is the "The reduce output key type".
> Its probably just a c&p oversight since the same methods are present in the
> MapReduceDriverBase class. Here the generic {{K2}} is the mapper output key
> though.
