    Description

      GenericWritable currently uses Class.newInstance and it should use hadoop.utils.ReflectionUtils.newInstance. Furthermore, GenericWritable should be Configurable and should configure the nested objects. This will prevent a lot of classloader issues and allow the objects to get a configuration.
