> Add kryo custom class resolver for faster serialization.

> Project: Giraph
> Issue Type: Improvement
> Reporter: Yuksel Akinci
> Priority: Major
>
> The custom class resolver allows kryo to always use the integer IDs for
> classes that are agreed by all nodes running the job. Default class resolver
> always writes the full class name of the first encountered class type to the
> stream, and then it assigns an integer for subsequent instances. These
> changes make the serialization faster by eliminating the need to write the
> full name for the first encountered class instance.
