> 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.
