> These changes add two new kryo serialization classes (KryoSimpleWritable and 
> KryoSimpleWrapper) which disable reference tracking at the expense of not 
> supporting recursive and nested structures. Disabling reference tracking 
> significantly improves the serialization performance. One a sample pipeline, 
> the running time reduced from 75 minutes to 5 minutes.
