Hi Josh, When I pass the fs.default.name with 0.6 version it works fine locally but not in
the cluster since it is looking job.jar in the wrong place.

I tried to get the latest code from master from git and compile it. For some reason it is
giving error and I cannot find the test classes in the  project repository.

> I am trying to use crunch to read file from S3 and write to S3. I am able to read the
file .But giving an error while writing to s3.  Not sure if it is a bug or I am missing a
hadoop configuration.  I am able to read from s3 and write to a local file or hdfs directly.
 Here is the code and error. I am passing s3 key and secret as parameters.
