looking at this, we do have to consider how much it matters that sequence
files with non serializable entries aren't readable.
that's actually defensible for minor releases according to the spec, so ok
for 3.6.0; not for 3.5.1.

> There's a collection of classes in org.apache.hadoop.io.serializer which try
> to bridge between Writable and Serializable.
> None of this code has been touched for a decade and may not be used; get rid

> Although tagged LimitedPrivate MapReduce, it may get used downstream in
> places like spark; which may notice if cut.
> so prune carefully.
