thank you very much it worked.
now that I have the files there I tried to run the jar file, and get this:
$ ../hadoop-0.16.0/bin/hadoop jar /wordcount.jar org.myorg.WordCount
/wordcount/input /wordcount/output
Exception in thread "main" java.io.IOException: Error opening job jar:
/wordcount.jar
at org.apache.hadoop.util.RunJar.main(RunJar.java:90)
Caused by: java.util.zip.ZipException: error in opening zip file

is there a downloadable jar file for the word count program from the tutorial.
I am sure that im compiling it fine, I fallowed the tutorial step by
step, and only get a error when I try to run it.
