> It is a recommended practice to reuse the Writable objects.
> DummyRecordWriter, which is used for testing in Mahout, however keeps the
> same Writable instance in a map: next time that the user reuses the Writable
> object, the internal map of DummyRecordWriter changes as well. This makes
> DummyRecordWriter fail for testing the MapReduce jobs that reuse the
> Writables.
