Sorry, I should have mentioned that I tried that as well and it also gives
an error:
$ <p...@hadoop01:~/hadoop_tests$> hadoop jar -libjars ./samplejoin.jar
/opt/hadoop-0.20.2/contrib/datajoin/hadoop-0.20.2-datajoin.jar

org.apache.hadoop.contrib.utils.join.SampleTaggedMapOutput Text
Exception in thread "main" java.io.IOException: Error opening job jar:

Has something changed or is my environment not set up correctly? Appreciate
any help.
