-------------------------------------

             Summary: Add kryo custom class resolver for faster serialization.
                 Key: GIRAPH-1188
                 URL: https://issues.apache.org/jira/browse/GIRAPH-1188
             Project: Giraph
          Issue Type: Improvement
            Reporter: Yuksel Akinci


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.
