Hi all,
I've downloaded last night build of Hadoop, and I want to run the
wordcount example. However I got an error:
[EMAIL PROTECTED] hadoopBuild]$ bin/hadoop jar

ANY idea what's going ON? I set this up on 3 machines, the set up is
actually pretty similar as what I told by the NutchHadoopTutorial. I only
modified the hadoop-site.xml, hadoop-env.sh and slaves so that it can work on
3 machines.
Any help will be appreciated.
William
