Description

For every URL/document to be deleted a new instance of NutchIndexAction is created in IndexerMapReduce (in multiple positions):

NutchIndexAction action = new NutchIndexAction(null,
   NutchIndexAction.DELETE);
output.collect(key, action);

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.
