Running first example

Hi all,

First of all, congrats for the project, I think it is awesome! I hope
I can use it and who knows maybe contribute (:
Anyways, I don't want to sound too clumsy but I was looking at the
project [1] and I haven't been able to run the first example which is:

{code}
./hadoop -jar ../../../ApacheCrunch/apache-crunch-0.4.0-incubating-src/crunch-examples/target/crunch-examples-0.4.0-incubating-job.jar
org.apache.crunch.examples.WordCount
../../../ApacheCrunch/apache-crunch-0.4.0-incubating-src/crunch-examples/src/main/resources/access_logs.tar.gz
.
{/code}

I keep getting this:

Failed to load Main-Class manifest attribute from
../../../ApacheCrunch/apache-crunch-0.4.0-incubating-src/crunch-examples/target/crunch-examples-0.4.0-incubating-job.jar

I am using hadoop 1.0.3 within MacOS and what I did is to download the
sources and run mvn clean install. Any hints?
Thanks in advance!

Are you running hadoop -jar, or hadoop jar? The latter is the right one,
IIRC.
