-------------------------------------------------

        Key: HADOOP-6162  (was: MAPREDUCE-738)
    Project: Hadoop Common  (was: Hadoop Map/Reduce)

> Since 0.18 (I think), SequenceFiles have supported serializing arbitrary objects through the serialization framework.  MapFiles still don't.  They require WritableComparable keys and Writable values.
