>    Affects Versions: 1.10
>            Reporter: Sebastian Nagel

> For every URL/document to be deleted a new instance of NutchIndexAction is created in
IndexerMapReduce (in multiple positions):
> {code}
> NutchIndexAction action = new NutchIndexAction(null,
>    NutchIndexAction.DELETE);
> output.collect(key, action);
> {code}
> Since the index action does not hold any data specific to any URL/document it would be
more efficient to re-use a single instance.
