Description

Sam Pullara sends me:

Phu was going through the WordCount example... lines 52 and 53 should have args[0] and args[1]:

http://lucene.apache.org/hadoop/docs/current/mapred_tutorial.html

The javac and jar command are also wrong, they don't include the directories for the packages, should be:

$ javac -classpath ${HADOOP_HOME}/hadoop-${HADOOP_VERSION}-core.jar -d classes WordCount.java 
$ jar -cvf /usr/joe/wordcount.jar WordCount.class -C classes .
