It seems that the issue was indeed resolved with the introduction of
SerializableWritable

> Spark should treat writable as serializable for keys

> It seems that Spark requires the key be serializable (class implement
> Serializable interface). In Hadoop world, Writable interface is used for the
> same purpose. A lot of existing classes, while writable, are not considered
> by Spark as Serializable. It would be nice if Spark can treate Writable as
> serializable and automatically serialize and de-serialize these classes using
> writable interface.
> This is identified in HIVE-7279, but its benefits are seen global.
