DistributedCache in non-distributed mode ?

Can DistributedCache be used in non-distributed mode ?

When trying to use DistributedCache in a non-distributed mode
development environment I am  attempting to add a Cache file with

 URI uri = new URI("http://192.168.0.201/cache/numbers.txt");
 DistributedCache.addCacheFile(uri, job);

I get the following error
java.io.IOException: No FileSystem for scheme: http

DistributedCache needs the HDFS to be up and running - so at the very  
least it needs a single-node setup, if not a fully distributed setup.

  If you wish, please open a documentation bug to clarify that in the  
tutorial/javadocs etc.
