Hi Josh , 

It build properly when I tried today building 0.7 snapshot. Not sure what different environment
settings I had yesterday. 

I ran the code with the patch and removing fs.default.name and it is giving me the same error.
  Also when I give fs.default.name it works in the local mode but not in the cluster mode
since it is looking job.jar in s3 dir.   I will get help of Dave [~dbeech] tomorrow and double
check if I am doing something wrong.

> 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.
