What's the difference between this and KryoWritableWrapper, when should we use one and when the other?

I have added more documentation now. The usage of KryoSimpleWrapper is similar to KryoWritabeWrapper. KryoSimpleWrapper can be used if the object being serialized is not recursive or nested, because it uses a version of kryo object that doesn't track references, hence significantly faster.

It would be great to switch to Java 8, to be able to keep this an interface :-)

Should we separate two Kryo implementations in two classes since they have a lot of differences?

Agreed, we can refactor the existing code to have a better code readability. I have added a TODO for that.

How will someone using kryo know which implementation to use? Can we add some guidance around that?

Discussed offline, @yukselakinci will in a separate diff refactor HadoopKryo.

Second PR for serialization. There is one more.
