public class DemoCountWikipediaPages
extends Configured
implements Tool

Tool for counting the number of pages in a particular Wikipedia XML dump file. This program keeps track of total number of pages, redirect pages, disambiguation pages, empty pages, actual articles (including stubs), stubs, and non-articles ("File:", "Category:", "Wikipedia:", etc.). This also provides a skeleton for MapReduce programs to process the collection. The program takes a single command-line argument, which is the path to the Wikipedia XML dump file.

Here's a sample invocation:

 hadoop jar cloud9.jar edu.umd.cloud9.collection.wikipedia.DemoCountWikipediaPages \
   -libjars bliki-core-3.0.15.jar,commons-lang-2.5.jar \
   /user/jimmy/Wikipedia/raw/enwiki-20101011-pages-articles.xml
