Description

when I follow wiki instruction: https://cwiki.apache.org/MAHOUT/wikipedia-bayes-example.html
(by the way, the bayes examples document in wiki need update to 0.3 )
to run step 5:
Create the countries based Split of wikipedia dataset.

I use the following command:
$HADOOP_HOME/bin/hadoop jar $MAHOUT_HOME/examples/target/mahout-examples-0.3.job org.apache.mahout.classifier.bayes.WikipediaDatasetCreatorDriver -i $MAHOUT_HOME/examples/work/wikipedia/chunks -o $MAHOUT_HOME/examples/work/wikipediainput -c $MAHOUT_HOME/examples/src/test/resources/country.txt

and failed on hadoop.
see hadoop log, it hint:
Error: org.apache.lucene.wikipedia.analysis.WikipediaTokenizer.addAttribute(Ljava/lang/Class;)Lorg/apache/lucene/util/Attribute
