> In both methods (addFileToClassPath & addArchiveToClassPath) you can specify a path.
If this path is fully qualified (hdfs:///....) the files are not in the job classpath.
> (since the : in the path is also used as path separator).
> So i think with one of the following simple improvements:
> - throw an exception if the specified path is fully qualified
> - OR disqualify the path (f.e. with new Path(path.toUri().getPath()))
> people would have an easier start with the DistributedCache!
