> Adding faster serialization classes.

>                 Key: GIRAPH-1185
>                 URL: https://issues.apache.org/jira/browse/GIRAPH-1185
>             Project: Giraph
>          Issue Type: Improvement
>            Reporter: Yuksel Akinci
>            Priority: Major
> 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.
