>          Issue Type: Bug

>            Reporter: Stefan Podkowinski
>
> In case SortedMapWritable is used as value in a reducer, the user must 
> explicitly call clear() on the map between iterating values. This is because 
> SortedMapWritable will be reused once instantiated, but consecutive calls to 
> readFields() will not reset the maps internal state, as e.g. done by 
> MapWritable. Please add this.instance.clear(); on top of readFields().
> You may also want to consider HADOOP-5028 for fixing another issue with this 
> class.
