>             Project: MRUnit
>          Issue Type: Bug
>    Affects Versions: 0.8.1
>            Reporter: Jim Donofrio
>            Assignee: Jim Donofrio

> We should not force K2 in MapReduceDriver's to be Comparable because Hadoop 
> does not enforce this on the map output key and value classes. This makes 
> MRUnit difficult to use when using non Writable classes that dont need to be 
> Comparable but define their own key comparators in the JobConf
> I realized this after seeing [1] on stackoverflow. I am still trying to 
> investigate if we have other conflicts with Avro
