Andrzej Bialecki commented on NUTCH-434:
-----------------------------------------
It should be enough to subclass GenericWritable so that it implements
Configurable. Various parts of Hadoop check for this, and set the current
Configuration on instances of such objects that they create.
> Replace usage of ObjectWritable with something based on GenericWritable

> URL: https://issues.apache.org/jira/browse/NUTCH-434
> Project: Nutch
> Issue Type: Improvement
> Reporter: Sami Siren
>
> We should replace the usage of ObjectWritable and classes extending it with
> class extending GenericWritable. Classes based on GenericWritable have
> smaller footprint on disc and the baseclass also does not contain any classes
> that are Deprecated.
> There is one problem though: the ParseData currently needs Configuration
> object before it can deserialize itself and GenericWritable
> doesn't provide a way to inject configuration in. We could either a) remove
> the need for Configuration, or b) write a class similar to GenericWritable
> that does conf injecting.
